lol, imo milkshape, 'useful' as it is, is not worth TWENTY QUID and never will be. Its a poorly made app and only good as an intro to modelling, there are better freeware apps out there.
stop creating a brush with invalid planes ffs! You're probably just vertex manipulating without realising how limited hammer/halflife are for brush complexity
simplest explanation without going into what its used for in RAD -
Stand in a room in halflife thats properly compiled The rest of the level is not visible around the corner (gl_wireframe 2 shows this) If it was the map would be unplayably laggy VIS works out, for every 'room' in the map, what should be VISible
I'm sure theres a guide on here or VERC (gak) for what it does in intricate detail
the NULL texture acts as a barrier and can be seen through, as long as it doesn't block VIS. To stop any crappy CS wallshot nonsense, just put 2 seperate invisible walls with a gap of 1 unit between them. No weapon can penetrate this (even the guass in hl)
I knew about it, have seen the sad matrix fanboys on the webbie and I'm saying its crap before its release because:
a) matrix revolutions (thats a reason btw) b) mmorpgs sap your life force c) enter the matrix d) er matrix revolutions (so important had to be mentioned twice)
a good p4, reasonable GF4 and a lot more ram should be able to run it Why you have'nt put more ram in I have no idea, it would speed up your pc no end!
there isn't a limit, but if you're trying to create some kind of 'looping' effect so it looks like you are moving but aren't, then you have to be careful as the game likes to forget to move the func_trains sometimes
