I'd have very few occasions to use Mari when thsi comes along. Sweet.
Peter Im quite new to SP, from my knowledge Painter cant compete with Mari on some other key features aside from painting across UDIMs, such as Projection Paint through, Warp tool, and direct 8k,16k,32k maps, although direct 8k maps would be sufficient for me, painter only bakes 8k currently so there is no 8k view port visualisation, only 4k.
