Just for testing light and textures, I took photos from a real life cafeteria and tried replicating the basic architecture in the Xed engine:
Pretty much nailed the eerie/liminal space aesthetic, althought it crashed the engine at least three times while compiling lights. Despite the limits, I like how you can work to generate a good enough map within few hours and fill it with custom made props within the limits of the engine. With a dedicated audience, I can see modders doing absolutely bonkers stuff with it once they get the tecnical knowledge right.
As for the other map, I've restaerd from scratch and enlarged a little bit to fit the kick-jump movement style better:
Next step will be adding enemies and working out the level logic like triggers, generator, forcefields ect... but so far I like the results.
