Pixel Processor - Ability to sample and map pixels using two position inputs
I'm running into a limitation with the Pixel Processor node when it comes to mapping pixels from the input image based on position variables.
Effectively what I want to achieve is map pixels from one position value in the input image to another position value in the new image. Think of it as mapping pixels from two different UV coordinates.
It would be handy to have an optional second input for the Sampler nodes for the Pixel Processor to control how pixels are sampled and mapped from one location to another because at the moment, I can only get position coordinates, I can't SET them.
This would be a very handy feature to have for remapping pixels more specifically for certain effects so I hope this makes it into Substance Designer one day.
This is technically not feasible with the pixel processor, as each pixel are processed individually and in parallel
