Nope, I just mean baking with a skew mesh (subdivided, with no smoothing, lowpoly) and using ray distance rather than a cage. In my testing this seemed to give much better results than a regular ray distance bake but it's likely I made a mistake with the regular RD bake as I can see no reason for the big difference; I'll…
From some testing I did the other day my conclusion is that using a 'skew mesh' is a pretty specific thing to do. By that I mean you will use it if you're getting significant skewing problems on an important mesh, or possibly (still need to do more testing here) if you notice significantly better results when doing a ray…
