| Hi All, I am trying to populate a 3D Max exported Terrain Mesh with lots of grass via code.
gem = CreateSprite()
SpriteViewMode gem,1
grass_tex=LoadTexture("./static/grass_green3.png",2)
ScaleSprite gem,4,3
EntityTexture gem, grass_tex
HideEntity gem
EntityPickMode terr,
For ll = 1 To 1500
ccx# = Rand(30,360 )
ccz# = Rand(126,385 )
cccopy = CopyEntity( gem )
LinePick ccx, 2100, ccz, 0,-22120,0
PositionEntity cccopy, ccx,PickedY()+2, ccz
Next
EntityPickMode terr,0
As you can see I am using 1500 grass pcs, but I really need 5000, but performance takes a plunge. So what do all of you other Blitzerz' do for grass ? thx :) |

| Normally, you would do your grass in grids - effectively look-up tables for more grass. You can buy a system for $12 USD (about £7) http://gothasoft.com/Software/ProductGrasspartyBE/tabid/105/Default.aspx |

| I have grass party, but after 1k in grass, it seems to lagg really bad also. I even emailed them asking why the code says it will support 120k grass objects but suffers after 1k and of course no response. My sys specs are not that bad (2.6 Intel, 2gig ram, N-7600 GS), so I don't really understand why the lagg is appearing. I tried a separate exe with just a terrain and grass without ANY game routines to see if it was my game, but still same problem. |

| From memory, Grassparty is a real juggling act. You have to make sure that it's own debug mode is not active - you have to balance ExtendedView and ExtendedViewMulti - plus AddViewDist and AddAnimDist - plus the LoadPerCycle Pretty much a faffing about juggling act to get it right. I seem to remember pushing the grass to 500,000 okay. However, if the above mentioned are not balanced then it can, as you say, lag. |

| I just use a good texture for the ground and only make grass when it gets close to you by linepicking down to place the grass. This is a good effect if it is done right. :) |
