OBJ uv into bufferGeometry with indexed drawing

Questions
1

So i wanted to use bufferGeometry with indexed draws, and… my .obj uv data is indexed seperately. how do i handle indexed uv data with three.js. is it supported?

vertex[1] may correspond to UV[5,7,8,2,4,6] etc. but i dont see an attribute for UV indices.

do i need to take my indexed data and make an algorithm to push faces with the corresponding uv data? because i would love to avoid that.

You exactly have to do this. three.js only offers a single index buffer for the entire vertex data. Simply because that’s what the underlying WebGL API expects. You can’t use WebGLRenderingContext.drawElements() with more than one index buffer.

Are you loading via MTL/OBJLoader ? I would expect it to do this unroll for you.
