I logged into preview a couple days ago, and tested a dimpled sphere. The dimpled ends tiled correctly - I was able to fit a 2 X 2 tile onto a sphere dimpled to .35. It was even on all sides.
Now, I've just logged in, and discovered that planar mapping has reverted to it's "broken" 1.8 state, where a .35 dimpled sphere takes a tile of 1 X 0.9 to look even.
I hope you guys get this fixed before tomrrow. I need planar mapping fixed, for a project I've been deep into.
