Texture Mapping

[AG124]

Does anyone here know how I or anyone else can fix the issues with texture mapping which are currently being caused by pack3d? I was having a look at another program (Blender) but I can't get it to work properly. :(

Although, here's an interesting tutorial for texture mapping in Wings3d. :hmm: Having trouble with it though.

I'll have to take a look at that. There are a lot of really great ship parts that can only be used on their parent models because they're mis-textured when placed on other ships.

If you have any luck with it, please let me know. Some of my texture problems are severe, although I am now choosing parts which fit better.

I am a newbie here, but allow me to give my 2c :
Problems happens in models when their parts are multimaterial. Or Multi/Sub Materials as the call them. Assignment of materials to subparts is incorrect, but it comes from *.mtl file which is part of the of the original data.
I think if we could "unscramble" that text *.mtl file and put the materials in correct order the problem should be resolved.

I may be also that *.mtl file is missing one on the materials on the list. Why I am saying this? When I subject the multimaterial model to script splitting the model into the individual submaterial parts - one of the part is dissapearing.This leads me to conclusion that something (material) is missing.

thats not a bad idea Polak2
can we not use the *.mtl generated by pack3d to fill the missing data ?

Further investigation how 3D editor "sees" extracted 3D multisub objects yielded more complicated picture:

Notice that for example Mat#1 which is concrete2 has no vertices and faces which is INCORRECT, same with last one Gate_D which shows to be on ALL elements of this model. This is also wrong.
Those materials in between are also incorrectly assigned, but they may not appear so evidently incorrect as the ones I used as an example.

What I am trying to say is this: all known 3D editors which we use to edit extracted models may get wrong/scrambled picture from extractor. Of course that only applies again to Multimaterial objects - the single materials are OK. I'll keep up some more digging.
