Hi. This is a method I came up with and originally shared on chamferzone, but since I can't see any evidence on someone using it before me I feel I'd share it to a wider audience. The concept is that when you're creating a highpoly to be baked later onto your lowpoly, if you use floaters they'll often get distortion…
If you bake in Toolbag 3, you can fix skewing with the skew paint tool, just paint where you have floaters or skewed detailed to correct the problem. No need to edit normals, bake and mask multiple maps or anything like that. https://player.vimeo.com/video/190166224? More info…
