This is the exact turotial I have been looking for. Thanks Chris!
I am having one issue with the painting on a render target. It seems like when I move the character too far from 0,0 the ni system hits the edge of the texture and can’t paint any further.
I found that if I increase the world size number, it does allow it to go further, but then the amount size of the mask becomes huge. Any idea what might be happening?
