Hallo,

ich habe den Shader mit den Detailmap Änderungen versehen. Allerdings wird angezeigt, dass das meine Hardware nicht unterstützt.
Habe ich etwas falsch gemacht oder kann ich diesen Effekt nicht auf einer Geforce 4 Ti 4200 nutzen?

Vielen Dank für die Hilfe!

mul r0.rgb,r0,t3_bias

versuch mal bei mul das _bias wegzulassen:

mul r0.rgb,r0,t3

und verwende einen leeren fallback:

technique fallback { pass p0 { } }

auf meiner geforce4 ti4200 funktionieren die meisten shader nicht wenn keine leere fallbacks hinzufüge! sehr seltsam...

Hallo,

so langsam wirds mir peinlich

Ich habe deine Änderungen eingefügt. Allerdings kommt entweder eine Fehlermeldung wenn ich den leeren fallback um den Shader lege, oder es wird kein Multytexturing angezeigt wenn ich die Zeile nur über den Shader schreibe.
Warscheinlich habe ich nur irgendwas falsch verstanden. Aber ich befasse mich erst seit kurzen mit Shader effekten. Ich bitte meine "dumme" Frage daher zu entschuldigen
Danke für eure GEdult.

Any screenshots for the Pixelshader support impaired?

I am working on learning the shaders. But have a couple of small shots here:
http://steempipe.technicalfoundry.com/terrainshots.html

This is using Vent's stock multitexture shader.

Just some one-offs for comparison. The shader is using (1) Grass Tex, (1) Dirt Tex, and (1) alphamap for blending.

Small pics, and not *very* exciting, yet.

die fallback technique muss hinter der multitexture technique stehen!

Hey-

Not to cross post but I thought I might get the shader gurus attention more easily in here . I am having a few glitches with the shading of the terrain when using this shader. Any ideas/help would be appreciated. You can check out some shots snd more info here:

http://www.conitecserver.com/ubbthreads/showflat.php?Cat=&Number=339498&page=0&view=collapsed&sb=5&o=&fpart=1

Thanks.

Shots look cool, can't wait to buy my new video card

Trying to sort this out - I got that you have two tiled textures, and the shader blends between them based on an alpha channel that is not tiled. cool btw..

(what exactly is a detail map, is it overlayed on your tiled mipmap?}

Is it possible to have a map as a lightmap to do shadows (not tiled)??

thx.

Does this shader set light direction or affect the way that the terrain is shaded? I have been having some strange results (see previous post for link).
