Just after I posted this I found a fantastic model

I'm not sure who owns it as I found it on google. It doesn't have any edge IDs but you can put it together using pep designer
Working on the Lancer model as of yet. Sorry, community, but school has taken me away for the moment from making the weapons pep-ready. Also have to go back and fix some things about the longshot, too.
Keep ya posted!
EDIT:
Also took a look at that lancer... and It's just way too boxy for me. Going to try and finish the model, guys. Hang in there!
