[LVL ED] How do you make a well detailed level?

[Neelke]

I always start off by adding some particle systems, for example the fog particle. If you wanna use it, here are my recommendation color for prisons.

R=0.482
G=0.345
B=0.155
A=0.8

Adding some decals is also always something nice. The most common one to use (or at least for me) is the large dirt stain. Put it out on the map where you feel like it is necessary.

Another thing for prisons are welders. Usually seen either on the roof or on the wall. Like this one (download link)

Thats basically how I start at least. Others will probably find better solutions, but that's basically what I do. Or at least start with.
