CSTRIKE MAPPING: trees, 2d brushes

[m-d-freezer]

hr hr... ok lets start with the trees.

Trees can be both: brushes and sprites

If you want to make good looking lowpoly trees I can give you a littel tut here.

Make a cylinder with 3 faces.
rotate it that the 3 sided faces are on the left or right (topview).It should look like roof that turned upside down. Then copy this brush and rotate it (90°) that it looks like a cross (topview).Then put a tree-trunk in the middle and you are almost finish.
Last step is to creat a 4 sided box, rotate it 45° and sqeez it that it is only 2 units thick. Copy this and rotate it 90°. Put that cross in the middle of the another cross and you have an excelent tree.

Let me count ... erm ... 20 w_poly should it have
texture the unnecessary faces with the null or the skytexture.

-- finish --

You can also use sprites. Search after ''blazeer'' and u would come to his side where nice Tree textures are which you can put into sprite format.

I hope i helped you. See you soon

actually Day of Defeat (http://www.dayofdefeat.net) (another valve title) comes with a bunch of tree and plant models. You can use these for anything Half-Life.
Right now the only mods that support .mdl alpha transparency are DOD and the new CS.

This way you will save unnecessary w_polys, planes etc... plus model trees look 10x nicer and won't slow down the game as much as brush based trees would do.

I don't recommend sprite based trees. You can use them for plants and small stuff but sprite trees are really old school nowadays.

NOTE:
check out VALVe Collective (http://collective.valve-erc.com) and get the latest Valve Hammer 3.5 PUBLIC BETA. It has a couple neat new features including in-editor-modelviewing (3D VIEW) which will make it easier to clip and place models in your maps.

About your vertex problem:
You seem to be rather new to mapping. Keep in mind that Half-Life doesn't like coplanar stuff. Toy around with the vertex tool and see what it does and what it does not let you do. Basically everything you build has to be plane, so build complex stuff like terrain out of wedges instead of 6 sided brushes, don't overuse the clip-tool either. It might seem handy here and there but only use it when it's really necessary. And totally avoid the CARVE tool. It's evil.
Good luck
