Hi,

I updated from version 2025.4_v1.7.2 to this one, but now the rendering is very slow and unusable with old scene.
What is causing this? :shock:


I encountered the same problem today, but strangely, I was still using 1.8.4 a few days ago, and the rendering time was normal then (maybe 3-5 ...

You need to add the Tonemapping on top of the denoised AOVs, also ACES Tonemapping.

It needs to be done in Compositor so it is a bit more complex to set up, but it should be more easy in future, the devs are working on it.

Could you show me how I can integrate ACES Tonemapping ...

May be it wouldn't work, but it helps me fix crashes with old scenes and last plugin ...

Is there a reason why the GPU is not used 100%? Only in a few cases do I see it reach 100%.
I work on Win 10 with an Nvidia RTX 4090

I also tried version 2021.1.6 but it still crashes. I only have one texture displacement
It's looks like your geometries or vertex displacement. Having one displacement doesn't mean that will not crash. It's possible if you go high on tessellation.

It seems strange to me because the surface ...

I too have many crash problems with this version.
With Cinema 4D 2023 the situation is even worse! :(

do you have a more stable one for you? It looks like you're sending a report from 2021.1.5. Also there's a compilation error from geometry accelerator. Do ...
