Noob question: I'm exporting UV-coordinates from Houdini and I didn't see any mechanism of sharing UVs between primitives (let's assume triangles); each triangle has three vertices, and each vertex has a separate UV (like 0.3245, 0.9771). Is there any way of saying that e.g. vertex 2 of triangle 67 has the same UVs as vertex 1 of triangle 113 (instead of repeating the same floats)?
