I think it might be primarily when using R16. I've not had an issue with the 340.xx in R15, but within 2 mins of installing and opening R16 it had crashed

Well, personally, I can’t see any reason to put large numbers of GPUs on one system. It creates a much more costly single point of failure. MB, memory, cpu, PSU, or storage failure takes down 2 dozen GPUs? One GPU has hw issues and it takes down the other 23? No thanks. After hash rate, THE most ...

It's artistically great, but technically it's scanline of 1990.

"it extensively uses global illumination and physically based rendering... Combine that with the dynamic lighting, which has been rasterized twice for depth pre-pass, and a custom ambient occlusion solution which rivals HBAO ...

I don't think it's possible to do grouping and GUI changes for UserData... Also, since buttons are technically event creators and not data storage, you can't create button-type UserData. Closest you can have is a Boolean attribute that you check for value changes, then treat that as a button event.

I guess I'm drawn to Octane, and thus a GPU renderer, because i currently render using my CPU and it's not very fast. Granted, this is C4D physical renderer, so it may be that it's slower than Arnold, but I have a hunch that Arnold will also be fairly slow. I have a dual hexacore CPU (Intel(R) Xeon ...
