Unwrap UVW acting up

knak47

lately for some reasone when I apply a "Unwrap UVW" modifier it opens up on map channel 3. It never did this before it would always start at channel 1 unless I changed it. Also all my objects that I am exporting have 4 UV channels. 1 and 2 are my diffuse and light map that I intended on being there but 3 and 4 are just crap, and applying a "UVW Mapping Clear" modifier doesn't get rid of them.

It could be that you had Unwrap set to channel 3, then pressed "save settings as default" in the edit window menu?

There's an INI that saves these settings, the file unwrapuvw.ini in the plugcfg directory. Try deleting it.

Deleting the unwrapuvw.ini in the plugcfg directory worked, thanks. Although the "save settings as default" that was mentioned in the Edit window menu, I couldn't find one, so I am still stumped on how it got changed in the first place. I am still having another issue, my assets are still getting exported with extra UV channels that I never edited. And the Clear UVW modifier wont get rid of them.

Does it still happen when you start a new scene and merge all the objects from the original scene in it?
This happened to me before. As soon as I started assigning a second uv channel to a mesh the default became 2. Really annoying. Merging it into a new scene fixed it for me.

"Save Current Settings as Default" should be in the Options menu, in the Edit UVWs window. Look it up in the Help file.

To clear channels you should use the Channel Info tool in the Tools menu that is part of the 3dsmax main menu. Again check the Help file for details about how to use it, there are some caveats.
