3d Max Texture burn? 2004-02-26 - By Neto
Back
As Barry mentioned, there is a small problem with this approach: export the
model again and the texturecoordinatelist/vertexlist will have a totally
different order, and sometimes even a different amount of entries. That
makes it impossible to play copy the UVs from a model to another.
You'll need to do some lingo work to re-order the texturecoordinatelist from
a model so it'll match the other model. That can be done by checking which
faces have their vertices in the exact same position in both models, and
generate a new texture coordinate list in the proper order. Such operation
can take some time, so it's a good idea to store the resulting coordlist
somewhere (parent scripts, field members, or in the .userData property of a
3D member), so you can plain load it.
You'll also need to "split" the UVs in the destination model, to ensure
there are enough entries in the list to accomodate all the UVs from the
source model.
