Check whether UV1 is exist?

Unity Engine

Hello,

I am wondering is there any way to check whether UV1 of a model is exist? I can access the modelImporter of the model.

Thanks

Unity’s mesh API exposes all of the UVs:

If the primary UVs are not present on the model that you are importing, than I believe the API will give you all (0,0) for these.

Also, confusingly, when you say UV1, you might actually mean UV2. read the first several posts in this thread:
