Quote: "Do you draw everything out on paper first and then start putting it into the level? "
Rarely and only for ambitious projects. I would recommend it though.
Quote: "Do you use stock segments, entities and characters in your levels first to get them setup and running then make your own and put them in later?"
I dont own any more completely undmodified stock content but...why not? The stock content looks great if used right.
Quote: "Why would you make your own segments when you can re-texture the stock segments?"
Three reasons:
1: Its faster to use an FPSC tool like one from Doomsters Collection to make your own segments
2. If you retexture the stock segments...you no longer have the stock segments and you might need a lot more than these few.
3. The stock segments have a lot of meshdetails that might not look good with your texture.
Quote: "Do you do do your scripts as you go along or get the level set up and do that later?"
I get a basic level done, do the gameplay (scripts) finish the level. This is a good approach to keep an eye on the memory cap.
Quote: "Does anyone know where there are any good FPSC tutorials?"
If you updated your FPSC there should be the COMMUNITY GUIDE in your FPSCreator / Documents folder. A compilation of tuts by nickydude that will get you hooked.
If you want more, here are some of my tutorials:
