hey I have a whole lot of questions I need answers to:

1. How do I bend cylinders to create electrical wires and other things?

2. How can I make cuts to primitives? in my case cylinders.

3. I need help with my lighting because imo it looks like shit. can someone link me to a decent tutorial?

4. how can I fix the wierd light lining that I find coming underneath my walls from the rooms adjacent?

5. where can I find the texture that makes up those cool looking wires that I always see running from teleporters to the mainframe. I can add a pic if no one has any idea what I am talking about lol...
Help please?

for the wires im fairly sure its the same thing as question 1. Im not sure about the lights but for the geo, this guy has alot of good tutorials for mapping including creating and manipulating cylinders.

First I want to say, never work on lighting until geometry is 100% done, and always work on outside lighting first, then work your way inside.

"3. I need help with my lighting because imo it looks like shit. can someone link me to a decent tutorial?"

There are tool textures you can use to block light. "shadow   This texture applied to a brush will block light."
