Blender 2.5.9 and S3D

[Hans Witteman]

Hi mate,

Glad to see you sorted out.

Best regards Hans

If the material id postfix is missing in an mtl name (see the MTL S3D generates), S3D will first try to attempt to match materials by name, but will otherwise fall back to taking the order in which the materials are listed in the MTL file. So if the order is different, the material name not exactly matching that in S3D, and the id postfix is missing too, then it will cause incorrect uvmap index assignment as you have experienced.

There's a few ways you can work:
- always use material id's in the material name.
- always make sure each material name is unique (but this isn't always the case), but matching both in S3D and 3D app.
- if not, simply ensure you've got the same order of materials both in your 3D editor and S3D.

As such, I do not know why you still have this issue on your second attempt. Hope privateer can tell you.

Hi Mate,

I looked at the files and did an import with S3D.
Edit the MTL as you did the other building.
Blender is doing an oddball job on MTL things.
Why they would code it to do it that way is beyound me.

Add the cement texture to the assigned textures in S3D before importing your adjusted mesh.
You'll need to move the assigned textures in S3D up or down to get what you want.

I also saw that the original mesh has a few inverted faces so you may want to flip those.
And you may want to adjust the original UV's as the streakiness seems to be a weird UV layout when a different texture is used.

I have noticed the newer versions of S3ditor will render my ship's skins incorrectly. They show the exact same streaking problem. In the actual game engine they look fine. Not sure this is what's going on, but you might want to check.

Yes, You are right.
I forgot S3D does not tile the textures the way most 3D modeling programs do.
So you'll need to check in Game.
