Okay, I've used source for around 2 years off and on, and I've grown accustomed to how a large majority of it is brush based.
So I've been messing around with various other editors, and what I really want to know is, if I want to get anywhere as a level designer am I going to need to learn to model? as most of the newer engines I've seen had a large majority of models used for everything from terrain to props; With most brushwork (atleast from my attempts) not reaching the quality that could probably be easily acheived by one skilled with some modeling program.
Ive tried
*Hammer (HL2/HL1)
*Radiant (Doom3)
*Construction Set (Oblivion/Morrowind)
*Ued 3 (Roboblitz)
*Ued 2 (UT04, Red Orchestra)
*Sandbox (Farcry/Crysis)
So what I really want are your thoughts on what you think it would take to do well as a level designer for various engines...
