Here is a 2-second video. Note the pedal area on the exercise bikes, and the flickering that occurs:
This is from a file with four different Render Layers (attached). There is one Render Layer with the exercise bikes where the pedals are stationary, and another where they’re spinning. The goal is to smoothly dissolve between these two layers. It is working pretty well…EXCEPT…for areas where the Z-values are intersecting (or some-such).
Here’s a screencap of the problem:
Here is a screencap of the Node setup:
So! The end goal is simply to dissolve between the bikes, once again. I suspect the final solution will involve Math Nodes doing something with the Z-values of the problem Render Layers (2 and 3). However, I don’t know the solution, which is why I’m here!
Thanks for your help, as always. (For the record, KHorseman at IRC was the one who zeroed in on the Z values being the cause of the flickering. So thanks, there.)
