I have a problem in transferring UV's .I had a model which was unwraped in maya.Then we took the model to lightwave for doing the shapes.So before doing the shapes,we added some points on the base model in lightwave and made the shapes .Now we again brought the file to maya in obj format.Now i dont have the UVs.My problem is i am not able to transfer the UVs between the models since the number of vertices are not the same.How can i rectify this??
