Ive been investigating the use of grass on my terrains. Several games use this feature very well now,..such as the upcoming WISH and the established Dark Age of Camelot. Does anyone know what method they are using to create such dense and realistic grass?

It could be a fur shader, some programs have them. Or it could be simply many copies of a plane with grass texture on it. The second one would be easier to do with dark basic.

Fur shading would be cool,..I did a search for effect files but didnt find anything,..would you happen to know where the effects might be found?

Ive tried something with grass planes, but found that it tends to bog the system down as it take quite a few planes to create a realistic grass effect.
Pixel shader/effect would be interesting as I havent tried them yet.

You can speed up the grass planes by using code like:

Put that in the main loop.

Very Interesting Andrew,...!! I wondered about using the object screen command but thought that its overhead might be greater than the drawing of the grass objects,..Ill give it a try then.
Presently I check for grass objects in vacinity of my player and hide any out of htat range,..but im not yet hiding the objects that are not in view,..thanks

BTW I have been checking out the shader programs,..very impressive. Ive downloaded RenderMonkey and am starting to play with it (literally). Has anyone else tried shaders in DBPro with any success??

Hi DcZee,

For a wealth of information on DBPro shaders and some really impressive ready made ones, look at his thread:
http://forum.thegamecreators.com/?m=forum_view&t=28992&b=1
(ignore the silly argument that ensues on the first 2 pages)

One thing I would say is remove rendermonkey and download FX Composer from the NVidia website. Render monkey effects don't appear to work very well with DBPro, and although FX Composer ones need a bit of tweaking, they are a lot closer to the correct format for DBPro.

yes, i have a radeon 9600 XT and it works fine.

1 or 2 of the shaders are designed specifically for the NVidia cards, but the program works whatever card you have

If the built in rainbow shader from the demo works, then you should be ok - although I think your card will support them anyway.
