You can find a terrain shader with an rgb blendmap in the wiki, but it requires vs 1.1 and ps 1.3.

Yes, but it only uses 3 textures.

one stupid questions (i always have problems with the blendmaps to blend it correct o:O)

bmap sand = <sand.tga>;
bmap grass = <grass.tga>;
bmap road = <road.tga>;
bmap stone = <stone.tga>;

are this the blendmaps?

also i have a question about the blendmaps

if i want the road lying over the sand for example and sometimes the sand over the road. do i just have to do it with the alpha? (white things will be shown and alpha = nothing?)

cause i often have problems what teture comes first and how i let them blend over each other ^^''

DS_Kihaku,
Why don't try this tutorial here. Perhaps it could help you.

cause it uses RPG blendmaps and not sure if its always the same technique

I cant igure out how to blend the textures together on the terrain. can somebody explain what to do?

Nagashi made a magnificant simple demo:

The map with the simple colors like red, green, blue black, that is the blendmap.
