I'm coding a route and I don't know how to create station walls. Can someone tell me what I have to do? I appreciate any help I can get.
First of all you will have to build and model the actual wall. For that, you can either use a wall that is already available from another author, or you can code one yourself if you know how to (platforms are 1.1meters high so start your wall there, top it off at 4 meters; 25 meters long)
Then as said by others, you will have to go texturize your wall (unless if you want a blank wall or solid colors, which can be coded directly using BVE). Textures must be a square (128x128, 256x256 etc).
If you choose to use a photo as your texture, make sure that the photo is evenly lit (no dark corners) and is taken at a straight facing point of view (no angles).
