Well a blur dialate makes about as much since as bluring a uv. I have done it a far amount when using stmap. Defocus as well. In theory it shouldnt work but it does. Im guessing because of oh stmap samples. No subpixel. So its filtering solves some of the issues you would expect from the subpixel blur. I dont really know for sure never really thought about it just needed a fix and when normal doesnt work rules are made to be broken or at least bent a little. Not that I thought it would work but he was already bluring so what the hell give it a try. Its a single node. On Aug 7, 2014 1:13 PM, "Patrick Heinen" <[email protected]> wrote:
