Denoiser Question

neoman

I use the denoiser without any problem, except that for one character, if I put two characters in the scene, the denoiser stops working immediately and the image comes out grainy. Will you know why this happens? Thank you so much!

I believe that the Iray denoiser only works on the graphics card - thus if the second figure means the scene exceeds your VRAM and the render falls back to CPU then it won't work.

The denoiser only works with NVIDIA GPU renders. If your scene gets to big for the GPU and falls back to CPU, the denoiser will be disabled. Adding a second character probably made your scene too big for your GPU. You can use a free utility like GPU-Z to monitor the GPU usage. You can try using a product like Scene Optimizer to help make the scene fit in your GPU.
