Re: grid like artifacting with scale operations

Okay, just to conclude this thread, we ended up learning to work around the transform issues (a little blur here or there does wonders too), but also I found this fxguide article which goes over this whole issue, with various compositing appliations and transform algorithms, plus has some tips for the various applications at the end of it (for AE it is basically to limit nesting moves in precomps). Here's the link:
