Hallo!

I read many posts about differnt shaders here, but never found something like this:

I'm searching for a...

• MultiTexturing Shader, where two textures are blended and are used, of course, like a detailmap, so it looks really nice and realistic.
  
• Water Shader, that looks like a river.
  

Both shader should be able to be used with terrains and sould have (important!) a "fallback" function, so the terrains are shown normally if the player's video card doesn't support Shaders.

Does anybody know something like this? You can answer in English and German
Thank you a lot!
