Blender 2.5.9 and S3D

[blueduck]

Hello Mates,

I've got a problem using Blender 2.5.9 with S3D - hope you can help me!
I would like to change the mapping of the roofs of some buildings in the harbor_kit.dat.
As long as the object just uses one texture (TGA) there is no problem with remapping or moving the triangles of the object.
Just if I try to add a new (second or higher) TGA to the object, the object will be shown right in Blender but after the import into the harbor_kit.dat it will not be shown or the object looks completely “de-textured” with a mess in the textures.


Here is what I tried so far:

Started S3D with habor_kit.dat of Stock LSH3V5.1 and added the already present texture Bricks_roof_D.TGA.



Saved the modified DAT.

Then I exported the TGA files "SUBCENTE.TGA" and "Bricks_roof_D.tga" as well as the 3D-Model of node 2482, subnode 2478 “SubCenter_lod00” to the same folder as the TGAs



Export-Settings in S3D:



Then I switched to Blender, imported the Wavefront (.obj), selected EditMode, created a new Material “Bricks_roof_D_9d0740f” with part of the parentID of the new texture and assigned the new Texture to the material.

Selected 4 of the roof-triangles assigned the new material. Changed to UV/ImageEditor and “Unwrapped” and repositioned the triangles. I saved this state of work as a .blend-file because the result in Blender looks ok so far.



Then I tried to export this work to a Wavefront (.obj). Selected all Triangles (a-key) then chose “File – Export - Wavefront (.obj)” and tried different settings for the checkable Options.



No matter which settings I used (maybe not all or the correct combination) the import into S3D failed.

The settings when reimporting the OBJ are



And the result is not changed to the original:



Now I ran absolutely out of any idea what might be wrong!

I hope someone can help!
