Texturing splattering on terrain using blending.

Thanks but i know about the vertex alpha..

I ned to know is someone accaly made a good working Blending textures the same way vertex alpha works. but not entity FX32 witch disable zbufffer.

Reason for using blending is that it kepps zbuffer intact. and one can have paritcle fx and whater that dosent mix with the terrain in bad ways.

So please somone helpme sort out this Blending terrain texture.
