Some textures don't work...

[Luma3d]

I've been testing Vantage this week and notice that some textures don't carry through properly. See attached. One was rendered in max the other Vantage.

Are you referring to bump maps or something else? I see several small differences. Also, are you using the denoiser and is it the same without it? It would be best if we know the exact type of texture you're referring to.

[Luma3d]

Look at table base. The reflection is correct in the max version. The Vantage version is flat...almost like there is no reflection at all. Also the concrete floor. More reflection in Vantage, correct in Max.

Could you upload a screenshot of the material graphs for the table and floor from 3dsMax, please?

Also, are you using the denoiser in Vantage and is it the same without it?

Like Nikola said, we need the scene or at least a screen-shot of the shading graphs to tell you what's unsupported in this case.
Vantage does not support the full V-Ray feature set.

I am guessing in your case you have a blend material which we don't support currently.

I can send the file, but here are the mats the are rendering properly.

Yes, it's the blend material and also the normal maps. We will be working on those in the future.

However, before that we will implement the new coat layer in the V-Ray material. If you can use that, your scenes will be Vantage compatible sooner.

Can you still send me the file ? My e-mail is in my signature.

I switch the coat on and no change in the material. Dull as ever. I had the live link and was hoping for some real-time update. I stopped live link and saved the file and opened it up in Vantage stand alone. No update.

Hi Luma3d,

The coat layer that Vlado mentioned is not in the released build and is under development. Same goes for the Blend material, Normal maps and VRayMuiltiSub Tex. There is no ETA for the moment but we will inform you when they become available.

Best regards,
Alexander

I have been testing Vantage for some time and my textures have transferred ok until last week when Vray was updated and I started using some of the new Cosmos assets. Prior to using the new version of vray my model transferred with materials ok, since the update my materials do not transfer over. I have been in discussions with Chaos tech support but they just keep saying its my pc and a memory issue which doesnt explain why my model worked before the update, something clearly changed in Vray. They have since asked me to upload my scene from sketchup but even the link does not work.

The attached image is how my Vantage model looks, the roof should have tiles (standard vray texture)

Cosmos uses a texture format that is not supported by Vantage 1.0.2 but it will be supported in our next version, coming in a few days. However it looks like your issue is not with a Cosmos asset -- it's the roof. Have you changed your NVidia driver recently and which version are you using now?

I have done a test on an old project and the results show that there is an issue with the vrscene conversion from the new version of vray for sketchup.

VRAY-BEFORE: This image is of my project from a month ago which worked great

I tried exporting the same project to a vrscene and I received the attached warning so went ahead:

VRAY-AFTER: this is what happened to the same project that worked prior to the update and warning, as you can see all the materials have gone.

It is clear there is an issue with the vray conversion to a vrscene and is not read correctly by Vantage.

I have tried downgrading my NVIDIA driver to a Vantage suitable old driver and that made no difference.

Hi craig_williams,

Which are the two V-Ray for SketchUp versions that you've tested with?
If you've upgraded from V-Ray Next to 5 this might explain some of the issues.

The way in which material scaling is exported to the vrscene has changed in V-Ray 5.
The change affects Group/Component material assignments mostly.

To test this you can apply the rooftop material to the mesh faces and see if it makes a difference.
The thing is that the new method for storing material sizes in V-Ray is much simpler and more robust than what we had in Next but is still unsupported in Vantage.
Support for this will be added soon.

As for the interior scene - the difference there doesn't seem to be caused by the material scaling alone.
It would be great if you can share the project for testing on our side.
The file version saved with the older V-Ray will be most helpful.

Thank you in advance,
Konstantin

Hi,

Both Vray issues were Vray 5, I updated to the latest version of vray 5 with the added Cosmos addition on Thursday last week, this is when all the problems started. see attached version.

I guess this is just the problem that you keep referring to that the support for the textures will be added soon, I actually think its very bad that Chaos release a new version of vray which takes away some of the functionality and tell the customer we are working on a new version which will support these textures, you should just wait until you have ironed out all the bugs first then release it to users. I am frustrated as I have no idea when a further issue of Vray will be released and I am stuck with this version that does not work with Vantage.

Thank you for the report. You are lucky - the issue wasn't complicated to fix and today was the last day we could fix it before we release an update later this week. So you will have the fix very soon.

Details: Sketchup itself has a "unique" way of handling UV data, so our V-Ray plugin used some workarounds to export this for the V-Ray engine. The old workaround was causing some issues, so they changed it in 5.1 and Vantage wasn't able to validate the data and completely refused to load the UV set. However, there is still an outstanding issue with UV scaling when loading Sketchup data in Vantage -- this will be fixed in the future.
