Is it possible to encode vertex normals?

[FabianHummel]

Currently, objmc only encodes vertex positions and UV coordinates, but does anything speak against encoding vertex normals as well? Was this never considered in the first place, or was there anything that caused issues while trying to support this?

If nothing speaks against it, I would try to add this functionality because I really need this information for my shader.

it was considered but not implemented due to very inflated file sizes for larger models.
instead screenspace normals was used to calculate lighting.
it does mean that models can't have smooth interpolated normals though.

Thanks, I didn't know about screenspace normals, they seem really useful.
