Resulting OBJ should preserve MTL references

[vsantosu]

When the decimater succeeds, it strips off the mtl references. If I add them manually, the model looks great, but in some cases there are several references to the mtl file between faces etc, it is imposible to know where it suppose to go. This is common in models with several textures.

Can you show how to add mtl references?

Hi @heyyxd ,

to add a mtl reference to an .obj file just add:

mtllib materialname.mtl

I'm having the same issue here, I wonder if it's possible to merge all the materials into one before decimation to avoid this issue.
