[blender2.49]question about mesh

<< < (2/2)

kat:
Yes you can use "X" to simple delete the elements but depending on it it you remove that way, you may have to do a fair bit of rebuilding of faces etc.

I'm actually in the middle of writing up a tutorial on exporting models which goes into some details on why you triangulate. Basically a triangle is a 'base' element - like vertexes and edges which can't be broken down into 'smaller' elements - a quad isn't, it's composed of triangles so that extra bit of processing 'costs'. So yes, always triangulate.

I am looking forwad to The tutorial :)
I find a good way to replace decimate Modifier.
That's poly reducer(Mesh → Scripts → Poly Reducer ) ,which help me to remain the uv.
Because i feel more easier to unwrap  quad-mesh then triangle-mesh.
