Would the half life 1 engine render *this*?

Imagine the following scenario. Top down view, player in the middle of the room.



Obviously the surrounding walls would be renderd, but would the engine render them as a mesh, or as a whole poly? If you look at the seccond image, basically, is that red stuff that I've airbrushed going to be rendered? Its been a while since my quake 3 mapping days, but I believe, the correct thing to do would be to caulk it, as the player is never going to see it, therefore it doesnt need to be rendered.

Checkout my forum?

I dont remember clearly, but I think, most of the time, CSG/BSP gets
rid of all the faces that no one can see at compile time.

Edit: In your case, assuming a completely boxed room, the airbrushed faces will be removed. Just try it out.

Would a gl_wireframe and noclip show me what I need?

I believe all faces that are 'external' - ie open to the 'vacuum' of space outside the map - are removed during compile. That's why you get that weird blur effect when you use noclip to go outside the map- you don't see those outside faces like you do in the editor because they have been removed.

What exactly are you trying to do here?

To be more precise, only faces that are internal or touch a skybrush
are created during the compile process. :wink: No caulk (or, in HL terms,
null) texture needed for that, it goes automatically.

ah, I wondered wtf "caulk" was

the null texture is still useful and lets you pull off some neat poly-saving tricks within the map, though.

I <3 TEH NULL!!!
