Hello everyone! Been working on a video for the Saxxy awards for a couple of months now and i have to know something real quick before i make a mistake that may result in me getting disqualified.

Would it be ok if i were to use items that are in fact from TF2/Half Life but it's been slightly modefied like The Carl or suits that i personally never seen in the game like The Tie-In:

Sorry if this seems like common knowledge to you but it's my first Saxxy and i want to do good. I'm using music from "Audio Library – No Copyright Music" channel on youtube so i got that covered plus that i'm saving all links to music and props i'm using.

//Thanks
