I've included a screenshot of the game I am working, right now all the walls are just grey flat shaded so it looks awful. I need to make it look really interesting so that it's nice to be inside for a long time as well as easier to tell what geometry there is visually.
What techniques can I use to texture and light a world like this though? I first downloaded a bunch of square tiling images from a game art site but I realized they only tile a plane and you would get seams across corners: Would the solution to this be using procedurally generated 3D textures? How could I learn to do that and find out whether it can run on my low end computer?
I also don't know the correct way to do lighting, I think I would have mostly a lot of static lamps but I will also need a small number of lights that can be moved around. I have heard about multitexturing and know some games (like quake3) do precalcuation, so that may be an option but there are such a huge number of walls in a maze I worry that precalculation would take a long time and generate a huge amount of data.
I am using OpenGL and SDL in C by the way, it's my first 3D game and I got really stuck at this point since I don't have experience with 3D graphics programming before so it's difficult to tell which ideas are practical.
Any general resources or rough outlines about how I should handle this would be very valuable, thanks a lot.
