Your name is John White, an scientist who escaped from black mesa in a car. After 1 week of driving, you find yourself with almost no fuel, you enter in a warehouse but you doesn't find anything useful. In total desperation you use a crowbar to break a vent, only to find the beginning of your journey...
Demo Soon!
That's the way to go.. Varied textures on the ground and on the walls if I'm not mistaken do that in most of your rooms like that and it'll look epic. For example what you could also do to make it look even more interesting is to cut the wall brushes on the edges of those textured support pillars and then scale it inside the room a little bit.
That way the texture wont look flat and still looks correct. I do that sometimes. Doesn't work with every texture though. For some it looks good and for some just wrong.
I like this. Keep it up.
