Ich habe folgendes Problem mit terrainbasierenden Wassershadern:

In meinem Level befindet sich ein relativ grosses Meer, bestehend aus einer 1x1 hmp, welche mit Steempipes Rivershader ausgestattet ist. Um den Meeresgrund besser aussehen zu lassen, habe ich kleine Muschelmodels und Algensprites auf den Boden gesetzt. Doch da trat das Problem auf: Die Muscheln waren durch den transparenten Shader (tga) gut sichtbar, verschwanden jedoch, sobald ich mit der Kamera näher als ca. 300 Quants herankam. Warum?

Um herauszufinden, ob es am transparenten TGA der HMP liegt, habe ich dieselbe HMP mit dem auch beim Shader verwendetem transparenten TGA ausgestattet und einfach ohne Shader getestet. Und hier ging es wunderbar; die Models/Sprites unter der HMP waren sichtbar.

Vielleicht weiss einer der Shader-Gurus hier Rat?

poste mal den shader code hier den du benutzt...steempipe hat schon etliche versionen von shadern geschrieben

Wie gesagt, ich benutze Steempipes Rivershader, einfach mit etwas anderem Skin sowie leicht angepasster Waternoise... Hier ist der Code (nach dem Shader hätte es noch einen längeren Mesh Deformation Code für die Wellen, den lass ich mal weg)

Code:

Kennt irgendwer das problem, oder sogar die Lösung?

Why i can't see the effect? I just see a black block(the shader) and a bump on it(maybe the bump skin) Does my card support it??
A6 test level screenshot

Halo shader shot

Geforce Fx 5600 256MB? last driver :6.7

And why in other games like halo , shader works perfect the water shader and other shaders, ?

I'm sure the card suppoorts it... otherwise you would have had "effect not supported".

Is this using the stock textures from the demo of the shader?? If not, it may be more of a scaling and texture issue.

Many games have multiple effects for fallback to support a wide array of cards. Also, they (the coders) have more flexibility in how they program the effects as they are not limited to the same functions we are right now. They have more control over texture coordinates, the streams, and also multipasses, among other things.

for example the shaders of water that i download at ur werbsite don't work on my card! i just see the water as black!

And i used my textures for apply the shader above

And BTW what does the line command -emu does?? i read on manual...

Try this version water and you *may* see other than black. Good luck!
web page

If I recall, I have alpha channels in the riverwater textures.... long time ago so I may be wrong. What happens when you use those textures on your block??

-EMU??? Don't know, never looked into it.

it works perfect..so why i see the black thing? in other kinds of shaders?

Post, or email me (in my profile), the textures you are using. If posting, show the alpha, too.
