Im making a map at this moment, but i find Radient very fiddly to do anything in and not a very good interface overall (just for me thats all)
so i decided to go and make the terrain and models in 3DS max 7, mainly because i have the program and have a Certificate 4 in 3DS moddeling 
my main issue is that i may be able to make the models and terrain in 3ds max, but i still have the work with them in Radiant as well
i downloaded a plugin for max which i found on these forums, that exports .max files as .md3 (cheers to who that was btw).
this is as far as everything has gone right :banghead:
once i have the .md3, which part should i get it in with in Radiant >_>
i tried misc_model - came up with a retarted little box after i imported the .md3 and i was able to do anything with it
ive tried misc_gamemodel - same box >_>
im mainly asking this as max for me is far easier than radiant, and im only up to finishing the terrain
in advance thx
