Question

Regarding the issue of "Substance 3D Painter" consuming a significant amount of graphics card memory

The size of my source file is 409MB. When opening this file, the available video card memory reached 15GB (NVIDIA GeForce RTX 5060 Ti 16GB).
My job requires me to use a resolution of 4096. Even if I set the resolution to 2048, the video card memory will soon be exhausted.
At the same time, I also need to open the requirements file for the UE engine...

    Hello @????????ok,

     

    Substance 3D Painter has indeed some performances issue depending on the type of project. There are many things you can do to optimize a project (we usually advise artists to use Geometry masks as instance), but the most impacting solution is indeed to reduce the resolution.

     

    If you're facing performance problems, you can work in a lower resolution, but still export in the required resolution.
