I saw a nice post by Alberto309 on GB for making decent shadows for trees and thought I would make a tutorial for it.

Here you can see the effect in game, it looks much better.


I can only get this to work with Vluzacn's ZHLT compile tools Get them here


First make a flat null textured box about the size of the tree.

Texture the side that faces the light as {SHRUB1A and in face properties use fit to fill the whole face. (you can use any transparent texure that begins with { )



Now make the brush a func_illusionary with these settings

Render Fx = normal
Render mode = soild
Fx amount = 0
Light flags = Opaque (Blocks Light)

Add a wood brush for clipping, make this a func_wall but use the same settings as above.



add your model and then set your light_environment as below pic, you will need to play around with the yaw to get the light in the correct direction.



Thats it just compile.

Very nice

I used the func_wall in some map but not the func_illusionary...

Yeh use func_wall if you need it to be soild or func_ illusionary for bushes and things that you can walk through.

The bridge sides and fence in this pic are func_wall
