Persistent Issues with Vantage for SketchUp: Hoping for Real Solutions

Hello. I decided to make this post to list—and hopefully find solutions to—some of the most important issues my team has been facing when using Vantage for SketchUp.

I want to start by saying that I truly see a lot of potential in this tool. However, after a couple of months of testing it on real projects, both my team and I mostly feel frustrated. Vantage has very persistent problems that make the entire design process tedious and discouraging, to the point where it actually slows down our work. Most of these issues don’t seem related to how the tool was conceived, but rather to what we believe are bugs. Unfortunately, a large portion of the time we should be spending on design ends up being wasted trying to fix recurring problems:

- It’s very common that after applying a material or using one of V-Ray’s UV mapping tools such as triplanar (world fit), the object in Vantage either turns completely black or simply disappears. This is perhaps one of the most frustrating issues when working with Vantage for SketchUp. Sometimes the only workaround is to delete the object and then use Ctrl+Z to bring it back. In most cases, we have to restart Vantage entirely.

- Basic SketchUp functions like copy-paste or creating arrays take an excessive amount of time and very often freeze the computer, forcing us to use Ctrl+Alt+Del to kill both applications. This happens very frequently and only when Vantage is active. I’ve asked about this in other posts but haven’t received a solution. I even asked whether buying a GPU dedicated solely to SketchUp would help. I don’t know exactly what goes wrong when trying to use SketchUp and Vantage via Live Link, but working inside SketchUp becomes a nightmare.

- Vantage disconnects from SketchUp. This happens occasionally. I’ve noticed that once you’re in Vantage via Custom Live Link, opening the Asset Editor or Chaos Cosmos in V-Ray automatically disconnects the Live Link session. At that point, nothing you do in SketchUp is reflected in Vantage, and the only solution is to close Vantage and start over. It’s quite unpleasant.

- The mapping used in the diffuse channel seems to work completely out of sync with the mapping in the bump channel. Many times, to adjust the mapping of an opacity, normal, or bump texture, we first connect it to the diffuse channel since it’s easier to see the texture scale there. Once we get the mapping right, we move that texture to the opacity or bump channel. But this never works! As soon as we move the texture, its scale changes completely. And that’s not all—we’ve also noticed that even if we connect opacity, bump, or normal textures directly to their proper channels and do the UV mapping correctly, the moment we add a texture to the diffuse channel, the mapping we previously set for bump or opacity changes entirely. It’s as if adding a texture to the diffuse channel automatically shrinks the textures in bump or opacity. The same happens with other channels like emissive. No matter how carefully you set your texture in diffuse, once you copy it to emissive, it gets rescaled.

- It’s not possible to save your work in SketchUp while using Vantage Live Link. Honestly, this feels ridiculous. The main reason we use Vantage is its ability to design and visualize in real time. Without Live Link, Vantage loses its purpose for us. A designer’s job is to create different concepts until finding the right one. Even after that, constant changes are needed—colors, materials, shapes. It’s essential to visualize them in real time. We can’t export a scene as a .vrscene every time we change a material just to see how it looks in Vantage. We depend on Live Link. If it doesn’t work properly and doesn’t allow us to save our work, Vantage loses all meaning for us.

- Beyond these bugs, there are many features that Vantage still doesn’t support or only partially supports. A very important one is triplanar texture in the bump channel. Not to mention other features that Vantage supports individually but stop working once combined. Honestly, Vantage feels like an unfinished application. And that’s surprising, considering it’s been on the market for several years and Chaos charges a significant price for it.

Despite all these challenges, I still believe Vantage has the potential to grow into a tool that truly competes with other industry solutions and makes our work easier instead of harder. My hope is that one day it will evolve into the reliable, streamlined platform we need. One that helps us focus on creativity and design rather than troubleshooting constant issues.

Thank you for the feedback!

Most of these issues seem to be specific to the Sketchup (V-Ray for Sketchup) integration.

- The first issue with the black/disappearing object is definitely a bug, but I wonder if there are some specific circumstances needed to reproduce it because I haven’t heard of it before. If it was trivial to reproduce I would assume it would have been reported by now. We will try to reproduce it but if you can, please provide steps or a scene to reproduce the issue.

- I commented on the large scene slowdown in the other thread you created. What I understood from the V-Ray for Sketchup team is that they have noticed a slowdown when using “observers” for scene changes and that Sketchup itself seems to take a long time to evaluate those. When live link is active our software needs a mechanism for tracking changes. They know of one potential alternative approach to avoid the slow observer mechanism, but as far as I understood this would require modifying a lot of code on their side.

- The issue where live link disconnects is again new to me, but it sounds like some limitation of V-Ray for Sketchup. I will ask them if they can fix that.

- Regarding different mappings, if I remember correctly this is handled a bit differently in Sketchup than in V-Ray for 3dsMax for example. This could be a bug or limitation on the Vantage side, though we do support some Sketchup specifics AFAIK. We will have to reproduce this and see what can be done. Actually, currently we don’t support arbitrary shading graphs for bump maps (such as UV transforms), but you said the same issue affects opacity and normal maps so it’s probably something else causing it.

- The inability to save during live link is entirely on the V-Ray for Sketchup side of things. Will ask them about this as well.

- You can vote for missing features on this site: https://chaosvantage.ideas.aha.io/ideas/?sort=popular We are trying to prioritize the most common requests, such as better bump mapping.

Hello, santiago_gutirrezdepierespedraza!
Thanks for sharing your experience!

Many times, to adjust the mapping of an opacity, normal, or bump texture, we first connect it to the diffuse channel since it’s easier to see the texture scale there. Once we get the mapping right, we move that texture to the opacity or bump channel.
There is some SketchUp specific behavior. Editing a Material’s texture from the SketchUp’s Materials Tray is available only for textures set in the Diffuse slot or in the Viewport Display > Texture > Custom mode. Adding a texture in one of these slots enables the “Use texture image” option in the SketchUp Materials’ Tray. Removing the texture from the Diffuse slot or/and from the Viewport Texture’s slot will disable the SketchUp’s “Use texture image” option. Adding a texture again in one of these slots will reset the previous size of the texture.
As a possible solution for preserving the texture scale, set from the Material’s Tray:

  • if you prefer to use the Diffuse texture slot → instead of removing the texture, just disable it with the checkbox
  • if you want to just see the texture scaling in the viewport while adjusting it (and to use the Diffuse slot for different texture) → use the Viewport Display > Texture > Custom > select a Viewport Texture from the slot.

Let me know if that is the case and the proposals help.

In addition, we logged in our internal system the following issues:

  • Coping and pasting an object with a Multi Material results in a black material - SK-5643
  • Resizing a material texture from the SketchUp’s Material tray is not updated during a Live Link with Vantage - SK-5641
  • Scene stops updating during Live Link with Vantage after opening Asset Editor for the first time - SK-5644

Unfortunately, the inability to save a SketchUp file when Vantage is started directly from SketchUp is a known SketchUp issue with “CFileException 0” when saving file . We are aware of that and looking into possible workarounds.

Kind regards,
Ivelina​

Hello!

A new way to launch Vantage Live Link directly from SketchUp will be implemented in the next major V-Ray version which will allow saving .skp file changes during the running live link. Also mentioned in this forum thread.

Regards,
Ivelina

What about the other problems?

Hello, @santiago_gutirrezdepierespedraza !

The issues with the resizing material textures from the SketchUp’s Material tray and the updating during Live Link with Vantage after the Asset Editor is started are also fixed. They will be included in the next V-Ray and Vantage released versions.
Various other improvements will also be added, which our developers are actively working on.

Best regards,
Ivelina

Hello santiago_gutirrezdepierespedraza,

Can you please try with our latest 3.2 release from yesterday to see if there are any improvements in the issues you are experiencing?

Best regards,
Alexander

Hello Alexander,

I’ve texted 3.2 extensively today and the issue with changes not caring over to Vantage still persists. I’ve prepared a simple scene where this issue can be easily reproduced. Let me know where I can send it.

Hi.
You can send the packed scene (from V-Ray>Pack Project) through our support portal (https://support.chaos.com/hc/en-us/requests/new) with the link from this forum topic in the message.
Thank you!

Just sent.

Honestly, Vantage for SketchUp is the worst rendering engine. I like it for 3ds Max, but for SketchUp, it’s a lost cause—always crashing, impossible to even save. I don’t think any SketchUp user would spend more than three hours trying to make it work, especially with all the other solutions on the market. Lately, even V-Ray is constantly crashing SketchUp or simply failing to start. In short, you really need to simplify things for the future, because even Unreal is becoming less complex and is a thousand times more efficient.

To be honest, it’s hard to stay constructive when the tool is this inefficient. Vantage works fine in 3ds Max, but for SketchUp, it’s just not there yet. There are so many great alternatives on the market today. I’m among those who don’t want to give up on V-Ray, but we’re constantly looking at what else is out there—and honestly, the temptation to make the switch grows stronger every day.

Santiago: our studio too has similar recurring issues as you describe but have found a couple of workarounds. To be honest we should have reported some of these sooner :frowning: Thanks for posting.

  • Objects going black. I find that this often happens when working inside a group of items. But exiting the group, and then cutting and pasting in place 9/10 solves the issue. Not ideal but workable.
  • Copy Paste can be slow to update but usually only a few seconds. I think its model dependant.
  • I find the mapping issues are often related to items that have been previously scaled in some way. Vantage/Sketchup seems to remember the original dimensions of the item that a material is applied to, even if it has been scaled before the material is applied. Its as if it has a default texture that it uses for mapping the new texture to and that remembers that its been scaled. The solution we use is to go to the VRAY UV tools and apply world tri planar (for anything orthagonal). Again most times this fixes the issues. Other times we need to restart.
  • Bumps + Saving files while in use are I agree a pain. Given the instability of Vantage on complex models (and Sketchup itself while operating vantage in tandem) crashes are frequent and we often lose work as a result. I do find that autosaves do work in the background though they again slow down production. (& despite the fact they say it needs to be closed to save, they are always there)
  • Caustics, bump-maps and better integration of displacement would be awesome to give better depth and realism and I hope one day added to the sketchup+vantage platform.

As for Julianne’s post above, I have to largely disagree. Our studio has spent several years now adopting it as our default real time rendering platform and have seen real improvements in the quality and adoption of rendering within our office. Yes it can be unstable at times, but often it doesn’t take much to find the culprit. (clashing plugins are common) Sorry it didnt work for you.

Would i like better integration with SketchUp? Of course. Are there features missing, yes. But it is evolving and to do so with multi-platform support is awesome. Continued support and development will only come from meaningful discussion with the developers at Chaos Group like this and sharing these issues.

Thanks for your feedback NRH1981.

I’m with Julianne on this. Vantage for SketchUp is a pain to work with. An expensive, unfinished product. The only reason we continue using it is because our entire library, built over many years, is in V-Ray. And since V-Ray or any offline renderer is no longer an option for us, we’re stuck with Vantage. Our workflow and client demands real-time rendering.

That said, we genuinely love D5. The team behind it is doing an outstanding job by listening to the community and delivering meaningful improvements with every release. Each update brings significant enhancements, and their focus on making the software streamlined, enjoyable, and productive really shows. The tools feel fast, intuitive, and thoughtfully designed, which makes working with D5 a pleasure.

Unfortunately, for the reasons I mentioned, we can’t make the switch just yet. But we truly admire the direction D5 is heading.

All we can do for now, and I think you should also, it to report all this annoying bugs and limitations that really slowdown our work as designer. Hopefully they will ACTUALLY listen and improve the software.

Hello, @santiago_gutirrezdepierespedraza !

Thank you for sharing your test scene with us. We managed to reproduce the issue on our side. It is related to editing a SketchUp component, not related to applying a material. It is actually reproducible even with V-Ray Interactive render, so thanks for pointing this out. I logged it in our internal system (SK-5770), so our developers can further investigate it.
As a workaround, the Interactive render or the Vantage Live Link connection can be restarted, which will update the render view with the applied material or with the transformed object.

Santiago, you mentioned in one of your posts an issue with updating the Scatter settings. Can you share which of the settings are not updated during the Vantage Live link, please? It will be helpful if you have a video of that. Thanks in advanced.

@NRH1981 ​, thanks for sharing your experience and workarounds!

Kind regards,
Ivelina

Hi @julianne_bernier , @santiago_gutirrezdepierespedraza , @NRH1981

Thank you all for the feedback!

I just want to share that V-Ray for SketchUp + Vantage workflows are becoming a top priority for us as we recognize our clients’ need for real-time rendering.
Some of the issues from this thread will be resolved soon - with the upcoming V-Ray 7.3.
A lot more improvements will follow.
So please, keep the feedback coming - it helps a lot to know what the top priorities (and problems) of someone using the tools in production, are!

And one more thing, we’d love to meet with each one of you and your teams and discuss this in a call (not a sales call - talking about 3D, workflow and ways in which we can improve).
If you are interested in doing this, message me in a DM and we’ll make it happen.

Regards,
Konstantin

This is another bug I’ve found in Vantage 3.2 Live Link. Right now it’s just impossible to use out of the box. Any change we make in SketchUp automatically sets the vantage Enviroment mode to Texture (see attached video). No matter how many times you set it to Physical Sky, it will go back to Texture as soon as you do any operation in SketchUp. This is a new bug that wasn’t present in the previews version.

Soon I’ll be posting some other bugs related to Scatter.

Hi Ivelina. These are just two examples. I’ll post more. In both examples you have to close to Vantage and launch it again to see the changes take effect. You can imagine how many times we have to do this in a single day, and how much it slows us down

This has made me wonder: does the person who adds these functionalities even test them? I mean, these are really basic functions, and it’s easy to see how they fail after some basic operations.

Hello, Santiago!
Thanks a lot for your reports!

The video shows what happens when you copy components with a Scatter applied, in this case some grass. The result is what you would expect: all new components have the same scatter applied. Now export that scene as a vrscene and open it in Vantage. You will se that all those scatter instances disappeared and only one of the components kept it (see attached image).
- Unfortunately, in the imported .vrscene files this is caused by the same names that the objects share when they are copies. This is also valid for copies with applied Fur geometry. These issues are logged in our system as LAV-2062 and LAV-2817.

- The both examples - with applying Scatter to an object and modifying spline with Scatter during Live Link are also reproducible during V-Ray Interactive render. The first one is a known issue (SK-5760) and thanks for the second one (now logged as SK-5781).
Another workaround is to toggle off and on the Scatter geometry which will trigger an update during Vantage Live Link instead of restarting the connection.

Kind regards,
Ivelina

Hi santiago_gutirrezdepierespedraza,

This is another bug I’ve found in Vantage 3.2 Live Link. Right now it’s just impossible to use out of the box. Any change we make in SketchUp automatically sets the vantage Environment mode to Texture (see attached video). No matter how many times you set it to Physical Sky, it will go back to Texture as soon as you do any operation in SketchUp. This is a new bug that wasn’t present in the previews version.

When in Live Link Vantage receives signals what has been changed and override local changes. When in Live Link session, changes made to the camera, exposure, render resolution, environment and scattered fog inside Vantage will be reset to their values or states from the host platform when:

  • playing animation/scrubbing the timeline/switching scenes in the host platform

  • navigating or camera manipulating

  • using Render animation with Chaos Vantage tool (available in 3ds Max, Maya, Cinema4D)

    It seems there have been some changes in the V-Ray export and Vantage now overrides the Environment mode and takes the one from SketchUp. It is recommended to think of Vantage when in Live link as a VFB and make all scene related changes inside the host app, in your case SketchUp. However we have made an improvement that preserves any local change made in Vantage. You will have the option to reset the local change to the one from the Live Link if needed. This improvement will be available in Vantage 3.3 around mid this year. For the time being I would suggest you do your changes in the scene where possible.

Best regards,
Alexander

Hi Alexander,

I’m not sure if I understood you correctly. My understanding is that normally Vantage Live Link should display the same type of Environment as in SketchUp (whether it’s a Sun or an HDRI inside a Dome), just like V-Ray would do. Therefore, all Environment-related changes should be managed from the host program, in this case SketchUp. Is that correct?

If so, that’s not what’s happening with Vantage 3.2. In this new version, Vantage doesn’t respect the type of lighting from my scene. Regardless of whether my scene uses a Sun or an HDRI, Vantage sets the Environment slot to an empty texture every time. This issue didn’t occur in the previous version, which did respect the lighting setup defined in my scene.
