i have uvmaped an object and now there is imposible for me to
change shader.
before i uvmaped it, i deleted the uv's. can that be the reason? But i have uv's now though

i gets this messege:

defaultNavigation -source lambert10 -destination |polySurface72|polySurfaceShape135.instObjGroups[0] -connectToExisting;
// Error: Error while parsing arguments. //
// Result: Dropped lambert10 onto polySurface72 //
