When you import, the engine often adds vertices due to normals or whatnot. How do you prevent this from happening?
I need my models to be correct vertex wise. Normals nor uv nor tangents matter. I’ve tried having an entirely connected uvs, I’ve tried 100% soft edge normals. I’ve removed all holes and I’ve tried triangulating.
I don’t think the importer adds vertices at any point. Can you post screenshot of you problem?
Hi Zafo,
Verts will be added based on the the normals edges for the polygon. If you are using smoothed edges then the verts will be connected however, if the normal is hard edged the polygon will be calculated as a single polygon with 3 vertices (one for each corner.
So for instance if you have a single vert that meets and the two faces are hard edged the single vert will be counted for each individual face. So that specific corner would have 2 verts and not one. This is how it works with real-time rendering for game engines.
