Custom Channel Data from Bitmap
I can use a scale op to take a bitmap's gray scale values and set the scale. That is easy.
How do I take a bitmap's gray scale value and put those values in a custom channel for other purposes? For instance: I'd like to drive the animation time of an actor with the gray scale value from a surface the particle sit upon. Could we have a way to pick a surface and texture map, grab a value and then set a custom channel value?
Or is there already a way to do this?
