@ Goku4Ever: Read the stickies all the tutorials are there
@SSJ4boneVegeta: I am 90% sure that 3Ds Max is not compatible (mapping wise) with Half-Life. Only Quake II and above. Try planetquake.com or something.
@ both of you: Don't make a thread and post here. Do one or the other. Just try to do things in this order:
1. Look through the stickies for problems.
2. Try a search engine on the internet.
3. Post.
This would cut down on the times I have to respond to you :S
