@alexander: as far as i know you have experience with direct3d programming. do you get such an effect to work with a simple direct3d application? ...maybe there is something wrong within a6?

@ventilator: Thanks for posting the cube map code.

Okay... what I have gathered this far is that there is a problem with some cards, maybe mainly GeForce, doing EMBM AND projected vertices at the same time.

Now what??? I have some ideas.... will have to work them out later tonight.
1). One option is to translate to vertex/pixelshader instructions.
2) Could also do a combo FFP and Vertexshader thing.

Here's the thing:
If this demo did not run on your card. Run the DirectX SDK BumpWater.Exe sample and see what it tells you. It tells me that it's running in the fixed-function pipe on my card. If it tells you it's running with a vertexshader, then we have a direction to go.
*Please report* what you find here. I want to translate things and ultimatley have adequate fallback techniques.

For those of us that like to tinker.... the BumpWater.Cpp is going to be our friend here.

Doesn't work on my GF2 MX400 either. Supports EMBM & 3 passes.

No luck on my GF fx 5600

i tried it on a radeon 8500. there it works... but that doesn't help me much!

@steempipe: if you use a projection texture you could try to render an inverted camera view to the bitmap you use for that. i think you would have a realistic reflection of the level then...

works great over here... radeon 9600 mobile (m10)
Fun stuff!

Ventilator- wouldn't using a render view to texture make this a pro ver. only shader? hope not...

yes, it would be pro only then. ...but i think this is what they do in far cry so it would be worth a try!

very nice!!! thanks for sharing this.

btw, every time i run the demo it reboots my computer after aprox. 45 seconds to a minute.

All I can see is 1 body of water, and it looks spectacular! 128MB Radeon 9800. BTW - Isn't there supposed to be 3 bodies of water? Thanks.

Correct, there should be (3) bodies of water. Are you seeing the one if you walk to the right? I am curious as to which effect file you are seeing.

@pocorev: Man, that is worse than just seeing black! Can't even begin to speculate on that one.

Looks like~ TextureTransformFlags[1] = count3 | projected; ~ is out of the question for most cards. Think I go out, cut the grass, and ponder this for awhile.
