[cgkit-user] shader.declare() for multiple RMLightSource()

[Rene <dar...@gm...>]

Hi,

I tried to set up a scene with two RMLightSource() objects and set the
shader parameters with shader.declare(), but it didn't work as I
expected, so I'm kindly asking for more information about this.

This is what I tried:

rmla = RMLightSource(shader=RMShader("ambientlight"))
rmla.shader.declare('uniform float intensity=.5')

rmlb = RMLightSource(shader=RMShader("distantlight"))
rmlb.shader.declare('uniform point from=(2,0,0)')

if I do that it complains that the shader doesn't have "from" (I
suspect it's because "ambientlight" doesn't have "from"). What am I
doing wrong? It's probably again some python mistake I've made,
because I still don't find my self at home with it.

Sincerely,
Daredemo
