Contains fast grass (with optional alpha-z-sorting by MasterBeaker), fast trees / forest Patches and experimental "volumetric" Fog Effect.

after a random number of seconds, (10 to 20) the entire screen will turn (blue/green). Looks awesome till then though!

It worked okay for me on a GF3ti - could be the volumetric fog - try stripping it out "GW"

blue/green? hu? Personally I had strange artifacts with any terrain in Blitz, but then I updated the catalyst driver for my radeon 9200SE (from www.ati.com) and now it works nicely.
Yes, the pseudo-fog thing might also slow things down unneccessarily. You can remove or remark it easily.
EDIT: GW - also try to use "Flip" instead of "Flip 0" in the main loop. Maybe that's the reason for your problem.

It works also with my AMD 1100+ and an GF1! Good work!
If I have the time, I'll go to add more sorts of trees and grases!

Very much indeed. Always interesting to see foliage systems working.

Like the code: speedy(on my aging system round 60FPS), but in it's current form it won't slip beyond the demo site though, hence the fence. ;-)
Never understand why people, when creating something nice like this, don't add more colors to the grassmap. For instance brown for trees, lightgreen for a hay type plant, darkgreen for plant type blah etc. This way you don't overwrite different types of foliage with each other and create the diversity needed to make it look more real.
Also wondering if the tree collision is constantly being active even if entities are not in view?(dunno how well Blitz3d handles that and if takes up time) In that case probably a zone system should be in place for larger terrains.
And as it's relying heavily on alpha it will of course give the dreaded troubles when adding other items to the scene.. Probably should change to a masked scheme, less pretty but will uphold in code.
Nevertheless, nice code to study on.
