Question by JoshuaJackson · Jan 27, 2011 at 04:17 PM · blender

Why models from Blender has more verticles, than they really has?

I have an model in Blender with 56 vertices. But after exporting it to FBX and importing into Unity, it says that there is 217 verts. I don't quite understand that stuff, maybe it happens because faces in my model are made of square polygons, and while Blender breaking them into triangles it duplicates verts?

In Unity all meshes are triangle lists but that shouldn't be the problem. A Vertex gets duplicated when it have a unique setting like vertex normal uv coordinate. A cube for example have 8 vertices but because you want each face to have it's own normals you will need 6*4=24 vertices. So only 2 vertices are shared on each side.

Converting quads to triangles doesn't add vertices. Vertices have to be split on hard edges and UV seams; what you see in Blender isn't what the model actually needs to be displayed by 3D hardware.
