Insufficient resources

[tonino_fadda]

Hi, I am working on a very complex scene and my PC is at the limit of its capabilities (I enclose a rendering of the scene made with VRay which took 9-10 hours on my machine). I have an NVIDIA Quadro RTX 5000 graphics card (16GB) and 128Gb RAM but I can't run renderings above 3K, Vantage crashes. I would like to know if I could overcome this technical limit by increasing the RAM to 256 or if the limit is the graphics card whose memory I am already using up. Thank you for your help.

No, that won't help, you already have enough CPU RAM.

OK thank you. I was advised to scale the distant vegetation textures to 256x256 so as not to overload the VRAM. I'll do some tests.

How do you scale the distance textures for a job like that ?

[tonino_fadda]

For the purposes of the test I will scale all the textures involved through a "macro" operation on Affinity (or Photoshop) and then I will reassign the texture paths towards the folder with low resolution textures from the 3ds Max asset manager. If the operation actually works I will have to think about how to adapt the future workflow (for example by creating alternative materials for the vegetation with already the low resolution textures). EDIT: there is actually already a dedicated function in Vantage for these purposes as shown in the attached image. I will try to exploit this possibility first.

When "Enable dynamic textures" = ON, which is the default, Vantage will only upload the largest necessary MIP level to the GPU. Of course there could be cases where a barely noticeable part of the scene is near enough to the camera to trigger loading a large MIP level.

The bias option can reduce the number of texels by 4 (when bias=1) at the cost of visible detail. You can even set it to more than 1, up to 2 (for 16x reduction) by manually entering the value, but it gets definitely blurry.

I this workaround doesn't fix the issue, but what if your render at a lower res, then upscale the image with Stable diffusion or Topaz gigapixel?
