I've decided, I want to do a Machinima, rather than a game mod.
I'm going to try to create custom objects, models, and possibly levels, and use Garry's Mod as a platform for executing said machinima.

quality machinima starts with quality actors
Anticipating Problems: I know I will run into problems during the making of this machinima, so it will be good to think of possible problems I will bump into that will hinder, or slow down, my process.
1) Getting custom textures + models + levels to show up in Garry's Mod
2) Will "these" computers have the processing power to record scenes for the machninima?
3) I've had a bad history with getting custom models to work in game (the dynamite)
4) Finding actors, voice actors, as well as a personal assistant.
Identifying Options/Solutions: I've to get my character to show up in Garry's mod. Something was wrong with the texture and it showed up in game, totally invisible. WHAT DO I DO?!
1) Keep trying. The model worked fine, I just need to get the texture to show.
2) I could do a test run next class, with fraps.
3) This could be something my team mate could do. Anyone want to work on my machinima team?
4) Find classmates/friends/enemies willing to do voice acting or as a "puppet master."
Planning Ahead: How am I going to finish this on time? Or more importantly, how will I finish this and still keep my sanity?
I could make a schedule, but its not something I usually do. Honestly, I'm just going to work hard, but trying not to stress myself out too much.
