My question is pretty straightforward : Is it possible (and how) to use multiple index for interleaved data.
For now my data is stored like this : Vpos1 Norm1 Texcoord1 Vpos2 Norm2 Texcoord2 …
I can draw the model easily with an index buffer but this means that the normal and texcoord are false because they have different indices.
4 2 0 -> Vertex position index
0 0 0 -> Normal index
0 1 2 -> Texcoord index
I am wondering if I could setup a second index buffer or interleave the index data in the current index buffer and just tell vulkan that offset 0 is for location 0, 1 is for location 1 etc
If that is not possible, what is the best way to pass the normals and texcoord in my case ?
