I'm trying to make a machinima using The Sith lords but i'm just so lost. I want to be able to build my own sets, and take full control of the camera. Please help my poor soul.

do you mean recording ingame or using an animation program.
if you want to do it ingame, i know scratch area building was just cracked. yuo can get the program for that and model your own sets, and then i use kotor tool to script your own cutscenes.

or you can just go into kotor tool, find the models you want, and export it to an animation program.

sorry if you need to no more, i'm pretty new to this myself.
