First question. I installed Arnold 6 on Maya 2019. It is written that Shadowmatte will work with the GPU, but this does not happen, it's just a black spot. Second question. All that I was able to render is the sphere :) I work in the automotive industry and not a single render has started. RTX 2080. There was an error about out of memory. Often I see that 70% of the video memory is occupied, although apart from Maya, nothing is running. How to solve all this?
