Material mix node input cause unnecessary evaluation when input mixing factor is int/bool
That is strange, I'm getting a very noticeable change in render speed. The difference is even larger with CPU. With 64 samples (1920x1080) using CPU I get a render speed of 2min 14sec with…
Material mix node input cause unnecessary evaluation when input mixing factor is int/bool
The performance issue was about .5 seconds in the previous upload, here is a new .blend file where I've exaggerated the issue with a more complex node network as the A input in the mix node.
On…

Material mix node input cause unnecessary evaluation when input mixing factor is int/bool
This seems largely related to how GPU runs the shader. Blender doesn't seem to build the evaluation graph differently based on these values.
I tested both Cycles CPU and GPU and both will…
