From my notes at the time:
I managed to create two adjoining spaces connected by a cylinder. Some parts are inside out because of... reasons. I’ve tried to apply a “Concrete” material to the cylinder, but it mostly just looks grey.
I think I could’ve textured these things, but that’s a complication I don’t want to deal with at the moment.
The inside out nature is due to the normals being in the wrong direction. A constant bane!
Why not just use a Quake map, I say?
In my attempts to make my life easier I found a way to import Quake 1 maps into Blender.
The Slipgate Complex is the first level of the Dimension of the Doomed. The level serves as a relatively gentle introduction to the gameplay of Quake (even on harder skill settings). It consists of two buildings with a small River) between them. The smaller building is where the player starts and it is relatively safer. The larger building is where most of the action takes place - it features several larger rooms, a large Slime) pool, and a series of platforms above it.
The textures are from a project to upscale the original Quake 1 textures. The lighting is also enabled, but it was neat to see.
Eventually I added in the jet model that you get from the SceneKit starter project. I was able to fly through the level, which was pretty exciting.
