I've never screwed with mapping, but apparently QuArK can do mapping, and that's what I've been using so far to do models. I don't think I'd recommend it for use though. It's 100% free, but if learning it for mapping is anything like learning it for modelling, then it's not very good. The documentation isn't very thorough or helpful for beginners. But on the other hand, if you're somewhat familiar with mapping already, then maybe some of the functions will carry over, I don't really know.http://quark.sourceforge.net/
GTKRadiant. Remember, dozens of the most popular games have been made with GTKRadiant & it's predecessors. Hammer has been used for..... five. Hammer is the odd one out.You might be able to find old copies of worldcraft somewhere. That's what Valve bought to make Hammer from. Before Valve bought it worldcraft supported id engines, like Radiant. There's also been Hammer users who use that to make maps for id engines.
Is dis be it?http://www.fileplanet.com/44990/40000/fileinfo/WorldCraft-v3.3
try here... http://marlporo.pp.fi/aq2/software/worldcraft1.6.zipWorldcraft is all I ever use for mapping. Post back here if you need any help.
I looked at his page for a possible worldcraft d/l, I forgot what he uses.Sweet that he saved all the rust stuff.As for moving the camera... In the view window, holding the left mouse button allows you to look around with the mouse and holding the right mouse button lets you move the camera left - right and up - down. There is no forward or backward for some reason (if you find it lemme know). If you need to move forward you have to turn left at a 90 degree angle and then move right.It took a second to get used to, but I didnt have much else going on in the late 90's.As for entities, if you are clicking the light bulb button with an 'x' in the upper right, the box to select an entity from is on the right hand side of the screen with a drop down menu. If that is blank the FGD file is not pointed to correctly or missing.I dunno, I looked and it comes packaged with worldcraft 1.6. Its called quake.fgd, not quake2.fgd.A weird glitch, at least on my machine, if you use hardware acceleration for the 3d view window you cant select items/brushes in there with the mouse anymore... so just leave it software.
