Half-Life 2: Not Classic Windows game

What's there:
world brushes and brush entities
all the textures with proper scaling and quality
3d sky!
reflective water
Can probably do decals, overlays and sounds, it just wasn't the point.

What's not there:
-props
-terrain
-monsters
-ladders
-trains
-scripts
Some textures may be misaligned, this is a decompiler issue.

I did some basic replacements so maps won't require much effort to compile. Maps and textures are given with XashXT toolkit and Xash3D engine to avoid any hardship of Goldsource.

Use QuArK or Jackhammer or w/e to convert vmf to jmf or map.

I strongly advise Uncle Mike's P2ST compiler which I also include. Useful keys to put into map properties:

zhlt_maxextent 128 to increase fps and decrease compile times

zhlt_texturestep X to control lightmap quality

How to retain original HL2 colors:

p2rad.exe -dscale 1 -gamma 2.2
map compilers go to Half-Life folder!

Misc:

zhlt_worldluxels 0 1 2 to fix uneven lightmap on small details, or to fix seams

zhlt_nocsg 0 1 (entire map or func_group) brushes don't cut each other

XashXT supports overbright (see parameter in glsl\const.h) and external textures: materials\texture.tga

Run xash wih -help to generate help file.
