Shader kills lighting...

[tom_namibia]

Hi,

I successfully wrote my first shader, based on Zak's HeightBasedLandscape.fx to add some color to my landscape textures depending on the elevation.
Thanks Zak for this very helpful demo :-)

But now my lighting is gone...

The landscape looks as if it switched back to
Mesh.SetLightingMode(CONST_TV_LIGHTINGMODE.TV_LIGHTING_NONE)

Does a shader deactivates a  Mesh.SetLightingMode(CONST_TV_LIGHTINGMODE.TV_LIGHTING_MANAGED)?

What must I do to keep the LightingMode?

Regards,
Tom

You'll probably don't like the answer...

Using your own shader means you cannot use TV's internal lighting any more. Any kind of lighting you want to have must be computed in your own shader.

Basically, TV's lighting simply is a shader. By using your own shader, you override TV's one. So unfortunately there is no way to combine TV's light with a custom shader.

But it is not as hard as you may think. Standard lighting is pretty simple.

See Zak's tutorial for standard Blinn/Phong lighting shader:

I will test it now. Thx shadowsong.
