Re: [Assimp-discussions] Help with texCoords

[Mars999 <ma...@si...>]

Ok I am using this now and no more crashes...

    vertexTCData.push_back(scene->mMeshes[i]->mTextureCoords[0][j].x);
    vertexTCData.push_back(scene->mMeshes[i]->mTextureCoords[0][j].y);

So do I use the mNumUVComponents to take the place of 0 in the 2Darray? 
I am assuming this is for meshes that have more than one set of UV coords?

Thanks
