Hi there, I have just made the leap of upgrade from a GTX 1060 3GB to Vega 64 upgrade. This is mostly for gaming but I do (or perhaps now… DID) make renderings within blender cycles, but after the upgrade I noted some very strange issues. I have rendered a scene and the screenshots are below, the top images is with the 1060 (note the render time is less than 5 minutes, I was able to render GPU+CPU with my AMD FX 9370 processor). The lower image is with the Vega:
As you can see there are numerous problems. Firstly, I can’t use GPU+CPU rendering in Open CL, it just leads to a HELLA corrupted image (like the CPU blocks and GPU blocks are rendered entirely differently).
Secondly, and even worse, the scene isnt correctly rendered. The images on the walls are spotlights setup to project images on to the walls and it looks like they simply don’t render in OpenCL. Node setup is as follows:
Please can someone advise how I fix these problems? The GPU+CPU rendering is not as important, but the render has got to be made to render everything in the scene!
I am using AMD Adrenaline 19.1.1 drivers if that helps.
