So I'm looking for someone to make a shader for me!
Functionality is quite simple, every update it shifts the pixels of the image either up/down/left/right (or a combination). Pixels that are pushed off the edge of the image are redrawn on the opposite side, so that, if the image is seamless (like the one below), it would appear to scroll.
Would want to be able to run this shader on the animation frames of an active, NOT on an external image loaded through the shader.
Needs to work with RGB and Alpha.
The amount that the pixels are shifted needs to be controllable through 2 parameters (x and y, or u and V or whatever)
I'm happy to pay something around $30 for this - AND I'm happy to give this away to the community when it's done, because it'll be a super handy shader to have.
If you're up for it then PM me
