3DS max 9 - Unwrap UVW "+" option disappearing?

Kaination

I'm trying to make a simple buster sword, and I was following a tutorial, but whenever I try to select anything in the Unwrap UVW modifier, the + disappears.





Does anyone know a fix?

Its because you're applying the unwrap to a sub-object selection. Go back down the stack, and click the polygon button again to close the object. You'll see that grey box next to edit poly and the modifier disappear - its there to tell you that its acting on a polygon selection.

Yep exit sub object mode before applying unwrap. Push 1 (Toggles vert sub object mode) until "Editable Poly" is gray (it shouldn't be yellow), then its safe to apply Unwrap UVW.
