To speed things up, I usually render with two instances of Blender – one using the GPU and one using the CPU. However, sometimes something doesn’t work right – in this case, the CPU render was handling the texture a bit differently – check out the face and palms of the hands flashing off and on (on is the GPU, off is the CPU)…
Not much movement in this one, just a bit of swaying back and forth and a couple of blinks…
