UVW Mapping Adjustment Skews Bitmap

[jamisonlb]

I have a basic curved sofa that i modeled and Im trying to place a simple uvw box mapping on it and rotate and scale it. It is a crazy texture map a client wants and UVW unwrapping is not necessary. a problem im running into is as i rotate the UVW gizmo it skews the "box". It does not keep its shape and in turn skews the texture. Ive tried applying an Xform to the object, converting them to poly and back to mesh. nothing seems to let me rotate the UVW mapping in a non skewed manner. Ive attached two images as well as the file. As you can see when the basic mapping is applied and turned to box mapping the box appears oriented with the gizmo of the object but when rotated it gets crazy. This does not happen on any other objects in my scene.

Any help would be great!

I bet you have a hierarchy and some non uniform scale somewhere in that hierarchy..

I'll take a look at the model ..

thanks. I just realized i attached the entire working model by mistake. If that is a pain here is the sofa by itself.

Yeah - the object is scaled in a nonuniform manner. Hit F12 to open "Scale Transform Type-In" to see that : Absolut scale always should be 100/100/100. In your case those parts are member of a group that is scaled non-uniformily too.

 

So my recommendation:

Ungroup the parts, apply a Reset XForm modifier to each of the relevant parts, collapse the stack and reapply a UV mapping modfier again. Now it should'nt skew when rotating

perfect! thanks!
