vertex colours again

[jelle]

hi, im writing a terrain algorithm, and now im trying to assing a color to the vertices according to their relative height.

i've put the VES_DIFFUSE information in my vertexbuffers.

the vertexcolours didnt get activated however.

so i began searching the forums for this issue.
i've found that you need to disable lighting for your material.
i do this with

mMaterial->setLightingEnabled(false);

and then i use eg. phong shading.
mMaterial->setShadingMode(SO_PHONG);

now the vertexcolours get activated, but the mesh isnt shaded.
(it's one big blob of the same colour)

is there anyway to make this work?
(is it because i disabled the lighting in my code, and not in a material script?)

help greatly appreciated.
Jelle
thx!

If you are using 1.0.0, where vertex colours has been fixed, you can modify your material to use them for diffsue, ambient etc. Use

Code: Select all

mMaterial->getTechnique(0)->getPass(0)->setVertexColourTracking(TVC_AMBIENT | TVC_DIFFUSE);

Or in a material script you can define

Code: Select all

(...)
    ambient vertexcolour
    diffuse vertexcolour
(...)

Edit: Just to avoid confusion, using this there's no need to disable dynamic lighting; you can have both at the same time.
