I last attempted some serious UVing in Houdini over 7 years ago and now I am back there and running into issues, hence this thread.

OSX 10.9 . H 13.0.378

1) Select some vertices ,apply a cylindrical projection > set the U range to be 1 > 2 . The selected UV moves in the opposite U range ? . Apply a pelt and and change the U range and it works as expected..

I don't know if this a bug or some quirk with the cylindrical projection.
