semi-noob request with road modelling (lod)

[Moog78]

Hi,

I'm having my first attempt at creating custom roads and having some trouble get a working lod model.

I made the road mesh and it is working with _d, _p, _r maps the way I want it to.

I've made a simplified lod mesh but can't get it to work. I just want the lod to show vanilla asphalt and pavement so I have a name_lod_p and name_lod-r and these two cover the whole uv map between them.

When I start to zoom out, the road initially goes blue at medium zoom and then it appears that the lod works at long range zoom. The main and lod models are both created the same way and have the same orientations etc so I can;t see that the problem is with the mesh (although I am a novice with blender).

Can anyone offer any advice?

thanks

Is your lod model named correctly? As in does it have lod in capitals? For some reasons lods need to be name_LOD while textures are name_lod_d to work.

my God, that would have taken me WEEKS to work out. Thanks a million, it worked

Np and great to hear it worked! If it wasn't the naming I had no clue.

Maybe you can answer another question? I've noticed that when building roads, any free space in the UV map leads to blank spaces etc in the model in-game. This makes generating the UV map difficult as you can't have any islands etc and all free space has to be filled. It feels like I'm doing something wrong or missing something here, any ideas?

That's because it scrolls through the texture so it doesn't get stretched or squeezed. You can get around it with vertex colors, but for a road I wouldn't recommend it since short road segments wouldn't look good. It's better to just make the textures like the default roads and use space on the sides for some extra things if needed.

is it just the road surface that needs to be continuous along the axis of the UV map? If I'm using vanilla pavements does it matter if the pavement part of the UV map is not continuous?

I think it's just the road surface. The parts that use pavement might not need it. I'm not sure since I've only ever used it where it could scroll through the texture anyways.

cheers for the help, much appreciated
