I have been working on a Fixed-Function texture stage effect for mulit-texturing terrain. This is meant to be a fallback in the pixelshaders and also as an alternative.

This is using a 2 pass effect to keep stages under (2) in each pass. The textures are tiled using the texture transform matrix. The sand texture is blended using the alpha channel of a TGA.

I have included some fallback techniques, do not know if they are actually needed but I was having fun playing with this. I also may not be able test the fallbacks correctly. Feedback here, please.

This is done on 3DGameStudio A6.20.2 comm with a Radeon 9200 128 MB.

Goto my web site to get the Effect File, the Demo, or other info



This is adding another pass with a different alphamap and texture:



Please post mods, improvements, and if it does not work on your card please post the info pertaining to your card so I can know/learn.
