Yes at some point you will need to redo your UV layout, that seems to be the source of the problem.thanks ash i will try settle my problem
Gect is it i rearrange my uv layout then texture problem will settle??
Thank you, I've been wondering why that is....If your model was fine and has slowley started to lag your model might have build up quite a history when modelling, this can cause maya to lag as it is processing all this in the background.
To delete the history select the model and go to Edit -> Delete by Type -> History.
This clears the history and should speed Maya up.
