Hi,
every time I open a scene I always have this loading which takes about 1 minute. I wanted to understand what this was about and if there is a way to avoid it. Maybe I have to insert the Bake object for each texture?
Cinema 4d 2024 -windows 10- last build vray 6 update 1.2(v6.10.02)
thanks
Hello @visualtracing Please, be aware that it is expected for the software to take some time to load everything that the scene contains. Would it be possible to share the scene with us to take a look?
You can do that here or by submitting a request to our system: https://support.chaos.com/hc/en-us/requests/new
Please, do not forget to include all the textures and assets needed.
Hi Viktor,
I’m noticing severe slowdown using the latest builds when opening the scene. It take forever to create the preview so I’m forced to restart C4D, disable material previews from Vray preferences and reopen the scene.
It doesn’t happen with every file so is probably related to some shader created using the node editor on a specific scene.
Once opened I can restore the previews and it will work fine, I can even close and reopen the scene without issues.
Hi, @sirio76 Thank you for joining the conversation. If you could share with us a file that does that, we would like to investigate the situation further.
HI,
I have discovered that the cause of many of my crashes is due to this continuous baking. If I don’t do anything during the operation it goes fine but if I start doing operations many times it happens that everything stops.
I would like to know what exactly this baking is and what I can do to avoid it.

Hello @visualtracing Please, be aware that does processes such as Baking Viewport/Exchange Images are part of the Cinema 4D and not V-Ray. It’s possible it calculates the objects and material previews available in the scene.
For best answer, feel free to direct your questions directly to the Maxon’s support team.
It’s been happening to me since I used Vray, it’s due to the Vray materials, in fact if I delete them all the problem disappears.
I’m sure if I wrote to maxon they would say it’s a third party problem due to the plugin.
@visualtracing This is expected behavior as Cinema 4D needs time to load of the Material Previews. You could lower the quality from the Preferences ( Edit > Preferences > Renderer > V-Ray > Materials > Preview ) if you’d like: http://ftp.chaosgroup.com/support/screenshots/Cinema\_4D\_2023-11-28\_13-34-50.jpg
Hello All,
I’m going to revive this thread in hopes of furthering this situation because it hasn’t gotten better, for me at least it’s gotten worse. TLTR; Me and another artist I work with have been digging around the web to see what we could find on the material preview/exchange lags, lockups and crashes. Also what sort of baking is happening in the background when scenes are loaded in 2024. We’ve found that it seems to be an issue with other engines as well, redshift included, in 2024. Remember this 2024 release is supposed to have redshift “integrated.” Anyhow the frustrations are documented by users in the RS forums and reddit.
My question to those with this issue is whether you’re using node materials, and if its happening to people who work exclusively with Layer based materials? Also I don’t use it personally, but i understand that Corona has its own node slate editor - maybe a non-cinema node slate would circumvent the issue? Or maybe I’m wrong and the Corona specific node slate is in Max? - I’m hearing this second hand. Lastly, some people are commenting that the constant refreshing node mats(or never loading at all) is a cinema viewport issue. I have experienced this personally(and you might want to give it a try) where my scene stabilizes if I turn off materials in the viewport. The understanding being that Cinema has a messed up viewport setup where node materials have to be baked to show up in the viewport - OP brought up the possibility of baking but I think the status bar is referring to baking node tex for the viewport. The more node textures(some maybe 8k) the longer the bake. You update a texture, bake. You save your scene, bake. If it doesn’t bake, no viewport texture, just black.
Ultimately, I really feel everyone’s frustration - I personally work on big scenes with lots of proxy assets and hundreds of textures(some 8k) and being able to work in the viewport with materials loaded is pretty critical… RS users resort to turning off node mat previews, so the only time they see materials is in the IPR which perhaps isn’t an issue if you’re rendering small product on the gpu.
Any feedback or commiseration appreciated.
@wolfgang_himmelfarb @sirio76 Do you, by any chance have any update on the constant baking preview in Cinema 2024? I am having this annoying problem, especially in a larger scenes, makes everything very slow. I am on Vray 7.1 but I still keep working in C4D 2024, because when I installed a new release of 2025 and Vray 7 one year ago, everything fell apart. Till then I am scared to upgrade to newer Cinema since I have ongoing projects constantly. But if you have any update, did the newer Cinema solved the problem with baking viewport slowdown? Because it starts to be unbearable.
Any help is greatly appreciated,
Thanks.
I might sound like a crazy person but I disable texture previewing in the viewport when things get slow, primarily loading. My theory is that cinema needs a rewrite of the viewport. I have also found that classic materials help speed up texture loading and baking the viewport. If you have some basic assets that dont need complex node work, I’d recommend classic. So maybe its viewport+nodes that is the issue. I read somewhere that maxon never fully unified nodes and viewport for whatever reason - I’m not a software def so I don’t know if that true or makes sense. Regardless, I convert things like baked assets, trees or vegetation as classic layer materials - the set dressing stuff. I then use nodes for more complex materials I need to tweak a lot like; first plane, ground or hero assets. As far as migrating to 2025, I also avoid mid project migration. The one thing I keep in mind is that both cinema and vray have come a long way since vray 5 beta so there is no reason to doubt that new releases will improve.
Interested in what @sirio76 can add.
@wolfgang_himmelfarb thank you. I did try to disable texture previewing for one project few months ago. It was terrible and I worked on some textures literally withouth the preview, just by tweaking the setings based on experience. This project never recovered from disabling the textures and still loads them as black. I will try to convert as many materials to standard ones, thanks for that!
