Not sure if this section is the best for this topic (is there a forum section for dev related questions that are not necessary tied to Fusion?)
I need to find some way to paint tiles but see how it will look when the tiles are matched up with other tiles. So for example I might have a row of 3 tiles like so: OOO. But when I paint on the first tile I want it to update the image on all the tiles so I can see that it all matches up and looks good when tiled together. So if I paint an X over the first tile I want all 3 tiles to show this since they are identical. I hope my question makes sense.
I work mainly in photoshop, but for this task that will be made with pixel graphics I could also try some other program that supports this if photoshop don't?
