terrain texture splatting, fixed-function

Anon · January 30, 2011, 12:45pm

Its been a while. I was digging my old files and found this: p3dp.com/lib/exe/fetch.php?media … atting.zip
Im going to post this in the code snippets, but first I would like to know why the terrain isnt shaded without the shader generator. As far as I know Im only using 4 stages.

If you don’t use the shader generator, then any combined textures will be applied on top of the lighting effects. So if you want shading, you’ll have to multiply the result with CSPrimaryColor.

Yeah, doesnt this line do that?

ts.setCombineRgb(TextureStage.CMModulate, TextureStage.CSPrevious, TextureStage.COSrcColor, TextureStage.CSPrimaryColor, TextureStage.COSrcColor)

manual:

ts.setCombineRgb(TextureStage.CMModulate, source0, operand0, source1, operand1)
This mode is similar to “modulate mode”. The color from source0/operand0 is multiplied by the color from source1/operand1.

Or do you mean something else?
