Rendering problem with GPU: [Arnold]: 00:00:00 19328MB WARNING | [color_manager_ocio]

Hi
I'm rather new to 3DSMax and Arnold so please excuse me if this is a stupid question 🙂

I have trouble rendering a scene using GPU. The scene works with CPU. 

I get the following error message bellow and the rendered image is just black.

I use 2 NVIDIA RTX A5000 connected with NV Link. Am I doing something wrong or is the scene simply to big?

The color_manager_ocio message can be ignored, it has nothing to do with the problem (3ds Max doesn't have color management). Although it does suggest you are using an older MAXtoA, and should upgrade to the latest.

This is the problem:

Most likely there's not enough GPU memory available (there's a Min Memory in Render Settings > System > Automatic Device Selection)

Maybe it's textures?
Like in this case:

Thanks alot! It's probably the GPU-memory that's not big enough
