the condition in the pixelshader avoids sorting errors by making every pixel fully transparent or fully opaque. the directx settings i mentioned do the same but without the need to calculate proper lighting in the vertex shader.

...the original ati vertex shader only does a very simple lighting calculation which only fluctuates the brightness a little in sync with the waves...

Mit diesem Shader kann man bestimmt auch Haar/Fell machen, oder? So wie in der Dawn/Dusk demo

Hi,
@ventilator: Is it possible to avoid sorting errors without the pixelshader then? Or did I get something wrong now?
@Ex Citer: Tjo das wär sicher nicht schlecht
Aber dann müsste man wohl 2 Modelle mergen, eins für das Tier oder Monster oder was auch immer, und eins für die Haare, weil man den Shader ja nur auf das ganze Modell anwenden kann wenn ich das richtig kapiert hab ^^

the directx settings do the same as the pixel shader but with the lighting you want!

...
für haare eignet sich dieser shader eigentlich nicht, dafür gibt es andere techniken...

Well, that's why I asked whether I understood something wrong
I'm sorry but in fact I'm quite new to this, so I just didn't get this was exactly the answer to my question O_o

Hey I am having absolutely no luck with this one. Would someone be so kind as to upload a working demo of this so I can see what I am doing wrong? Thanks.

I can't get it work too

Would anybody be so kind to produce a small demo or just an example? This shader would be perfect for my outdoor levels

I think that grass shader is only working on terrain right? Could it be re written to work on leveltextures? And would it be possible to use Models (spike pits, (I have a texture called spikes. If a entity steps on the texture it looses. Putting entities into alle these pits of different size would be a big waste. I think a shader would do that better. Important would be the same distant of every spike). I hope the entity is faded out if its to far away from the cam (like detail maps, which are only rendered of they are close to the cam. The distance should be adjustable).

its as easy to implement. just place some gras sprites in your level and apply the action on it. just c&p the code from the wiki. there are no problems using it (if your card supports the needed versions).

I thought this shader was only working with MDLs?
@ExCiter: No idea what you think this thing was... but it hast nothing to do with neither terrain nor level geometry
