I'm having a similar problem... Though I managed to texture it in Blender, it seems that the object in Omsi Editor is white, it has no textures that I applied. I also used "Pack image" option while texturing, and I used bmp format...
Any help?
Seems like you haven't told OMSI what the texture is. Make sure you have done the following:
1) Created a new folder for your objects with subfolders: "model" and "texture"
2) Put the .03D file in the "model" folder
3) Put your texture in the "texture" folder
4) Put your .sco file in the main folder
If this didn't work, make sure you are not renaming your texture after export from Blender.
thanks, but i have some problems with the unwrap, i select all like the guy, but it doesnt appear....
Sorry I haven't been on recently so do you still need help or fixed the issue?
