Import all map tiles into Blender

[Titukis]

Hello, is it possible to import all map tiles to blender on right positions instead of them being at the same place?

[space928]

Of course, simply import the 'global.cfg' file: [image: image.png] Just be aware that Blender gets exponentially slower the more objects are loaded, so trying to load a map much bigger than Grundorf will be difficult (although you can get around this by using the new tile loading panel in the latest beta).

alright, this worked, but not all tiles loaded, some are still missing, what's the issue?

[space928]

I'm not sure, but there are a few things you should check:

• Do all the tiles import in OMSI Editor?
• Is the load radius setting set high enough?
• Do you get any errors while loading tiles?

If you're still not sure, I might be able to help if you provide the following information:

• What version of Blender are you using?
• What version of the plugin are you using?
• What map are you trying to import?
• Can you send the Blender log?
  • To do this open the Blender console like so:
  • And then copy everything into a new pastebin (https://pastebin.com/) and give me the link to the paste.

Hey, the issue happens when tiles are in the global.cfg file but not actually in the map :) Blender then can't find them, but it's fixable by removing lines of non existent tiles.

Also, I have other issue: how do I export the map tiles so I get terrain textures in UE? Everything I tried leads to white/black textures after importing. What settings should I use?

Terrain tiles use a somewhat complicated material setup which probably can't be exported by the FBX exporter (I'm sure you could write a script to do it, but I digress). You'll want to setup a shader in UE to match the shader in blender, the shader in blender for terrain tiles is different for each tile as each tile can have a different number of layers. Each layer has a main texture and a detail texture (as specified in the omsi editor) as well as a mask texture (stored in maps//texture/map/tile_X_Y.N.dds), the mask texture is a particular format of DDS that blender doesn't natively support (an ALPHA_8_UNORM) so I decode it manually (although I realise in the latest release there's a small bug in this), but this means that as far as blender is concerned it's no longer associated with a real file (it becomes packed in the .blend file). If UE supports ALPHA_8_UNORM dds files then that's fine, otherwise you'll have to convert it. A shader for a given terrain tile looks like this: [image: image.png] I don't plan on providing tools to set this up automatically for you. I struggle to see many legitimate use cases for exporting terrain tiles to UE beyond piracy.

I just need it for remaking the same map from OMSI. Maybe then there is a way to get heightmap photo from blender and use it in UE?

My source code is available if you want to use it to write a utility to export the heightmap as an image the import_terrain_mesh() function inside io_omsi_tile.py handles heightmap decoding and mesh generation, you could retrofit it to export the heightmap as a png.

Yeah, I would if I'd know anything about Blender 😆

As I don't plan to do anything further with this issue, I'm going to close it.
