Updated title - not Autofit, as it's a G3F clothing item on a G3F figure.
Sometimes Smoothing & Collision Detection works wonderfully, sometimes not.
I have Outoftouch's Superhose for G3F. For Victoria 7, it worked wonderfully. For Lien by Fred Winkler which requires Mei Lin, not so much.
What has me scratching my head is that it looks perfect in the preview window. But when it renders, there's lots of poke through all over the place. I've messed around trying both Base Shape Matching and Generic for the Smoothing Type, and bumping up smoothing iterations as high as 100. It has some morphs which don't work very well in her case. Not to sound too picky, but with stockings a smooth fit is essential since it's partially transparent.
It's a Genesis 3 clothing item on a Genesis 3 figure - seems it should work better. Am I missing anything?
