I couldn't say for sure, but the Oblivion long grass looks like it's done with clumps of alpha-tested billboards, much like trees are often done. Underneath the slates is a regular planar grass texture, potentially normal-mapped.

Is this what you mean? As far as I can remember, Morrowind didn't have any such grass.

Grass rendering isn't the easiest of all things. There are many, many techniques out there, and usually a few of them are combined to achieve a proper LOD system. I recommend checking out some of the following:

- Vterrain.org
- Graphics Forum FAQ
- Past posts in the Graphics forum
- NVidia SDK

I actually already look at all of them so I'v come to a conclusion. I need to use RGBA color components of my vertices to proform my blending operation on 4 textures like the first one uses the red component for its level of transparence the next one green and so on so is there a way to do it without shaders?
