    What does this error mean?

    Code (csharp):
    1. Program 'vert_surf', output semantic attribute "TEXCOORD" has too big of a numeric index (8)
    I have almost identical one about 'frag_surf'

    thank you

    you can not have more than 8 sets of UV coords on a vertex I think -> index 0 to 7
    on the texture side it can have up to 16 coord sets because you can push through 16 textures per pass on some hardware and you need to be able to extract data from them.

    technically unity does not import more than 2 uv sets per vertex from an fbx anyway.
