http://img332.imageshack.us/img332/9692/eycompo00007cl.jpg When I look at that part of the cliff it disapears and when I walk closer to it I can see it normally again! The part that disapears is made out of many part of brushes not full ones! I'm using direct3D! And whats causing it? How can I fix it and will it be seen in openGL too? (I can't use openGL )
Well I'll tell you how I usally make it(and I never looked in that example map! First make a block for the glass(don't make it transperent) and on the side you want the player to see through texture it with the null texture and here you go! If you want then behind(in the transperent side) you can place a regular glass brush(transperent) so it will look more glassy!
Where should he write that parameter? I gess he should in the CSG but maybe in the bsp? Anyway you know whats an origin brush? If you know then find a rotating object and check if it's origin brush isn't in the void(or partly in there!
Carving is bad cause it's uncontroll able! You don't know how it's going to cut staff(to how meny parts) and what it's gonna carve(it sometimes also carves object that it doesn't touch) : Well If you are really a begginer and you want first to know hammer then you can but as you learn more and more I suggest that you will move to clipping!(it's like carving manually) Here is a tutorial on cliping holes in walls and making hallways!
Where d'heck is that sound! I know it's in the pak but where and what's his name? And after I found that sound will I need to put it in valve/sounds/... or import it into the pak?
Mmmmm...can I make how can I make that if I'll climb a cilff or a rope there will you will hear no sound and when you wil climb a ladder you will hear the rgular one! : And I'm willing to change the .wav or what ever it take! But it's for the compotition so I must use Hl1!
