deleting faces on a brush

[g8rjosh]

I want to delete un-seen faces off of a brush to make my map run smooth without having to render it. How do i do this?

Well, you dont delete em, rather you use the nodraw texture. I like to make the entire map with nodraw only then only texture visible faces. Makes the process faster and easier I think.

sock is right, you can't delete a face but you can tell the engine not to render it with the nodraw texture.

The truth is this though, it's not going to help you that much. If your map is running poorly now chances are using nodraw on your unseen brushes won't cure it. The engine already deals with a number of unseen brush faces anyway.
Your best bet is to optimize visibility and geometry in the map. Valves Optimization Guide should help you, just be patient with it.

stick a nodraw texture on there though it won't help optimize more than a little

good construction and hinting is more important than obsessing over every unseen face. plus i think faces that cannot possibly be seen wherever the player stands are automatically culled anyway

Since we're talking about optimizing, one way to reduce compile times hugely is to change the lightmap size on faces. Faces that are fully in shadow don't need a high res lightmap, only faces that have a shadow casting across them need a decent sized lightmap.

sock im not much of a mapper but ive made a good few maps in my day. i cant image making it all in the nodraw texture n then texturing it. i get dizzy enough cycling through it with textures lol. ennui does it only optimise it a little? what about those maps that have huge unseen areas covered in no draw texture?

I like to make it with nodraw, but put the view mode to light map texture, it gives it a bit of shading, so your eyes can pick up stuff easier, and its easier on the eyes too. : p
