I'm sorry for necromancy, but i had to share this, if anyone's ever felt frusterated with Hammer.
I was getting irritated at Hammer's distinct difference from MOHRad, such as camera controls (debatably nicer), texturing, placing entities, and the like.
So instead of getting used to a new way of doing things, i (as i am wont to do) adapted how i'm used to to how i need to do it.
You can make a basic map (i used test_firefight.map) and load it in Hammer, you simply need to move it to the
C:\Program Files\Valve\Steam\SteamApps\<login name>\sourcesdk_content\hl2\mapsrc
folder structure. Open Hammer, select Open, change the openable file types to WorldCraft Maps, select your map and be amazed
HL2 and MOH follow the same sizing proceedures, roughly.
DO NOT make entities, detail brushes, or anything but normal brushes, do not texture them or place static models. If you do, they will show up as a dorky yellow picture saying "Obsolete" and any detail brushes will come up as errors (x solids were not loaded)
sorry, sounds restricting, but if you'd rather work in MOHRad then Hammer, this is how to do it.
Probably complete spam, but i thought i'd let you all know... in case you sed Hammer.
