Getting Uv Coordinates Of Vertices

[ehmdjii]

hello,

i know this is probably pretty easy, but i couldnt find it in the docs yet.

i am looking for a short script that returns the uv coordinates of all vertices in a mesh.

usually uv coordinates are for each vertex on each face, so a vertex can have multiple coordinates, but in my situation this isnt the case. all i need is one pair of coordinates per vertex.

thanks!

Here's the basics, I'm sure you can re-arrange it to your needs.

string $selection[] = ls -sl;
int $numUVs[] = polyEvaluate -uv;
for($i = 0; $i < $numUVs[0]; $i++)
{
print ("=====\n");
print polyEditUV -q -u -v ($selection[0]+".map["+$i+"]");
}

thanks a lot!

do you know if these UVs in the map arrray are in the same order than the vertices in the vtx array?

Since you cant be sure the number of UVs is the same as the number of verts you should always use the polyListComponentConversion command to get your UVs from your verts. The order of the .map array might be the same as the .vtx array, but depending on it being that way is just sloppy programming and asking for trouble.
