[CsMain] light n values for render

2008-02-27 Thread infinity 
In the CS manual it says, or seems to say, that multiple lights can be
available to a shader program, (cg language shaders in my case) like light 1
color for example


Lighting
‘N’ denotes the light number. The first light is light number 0. The upper
limit for the value of ‘N’ depends on the shader as well as the render loop.

  ‘light ambient’
  Ambient lighting color.

  ‘light N position’
  Light position in camera space.

  ‘light N position world’
  Light position in world space.

  ‘light N transform’
  
but I havn't been able to get this to work with any settings, only light 0
is set. I can see it set in the source code too, but no other lights are
set. How could I get this to work?

thanks, I didn't know about that.
One reason you would need that is the renderloops draw things multiple
times, and since it's not done for objects, the render priority etc isn't
having the right effect.

Well, can does not mean is :P In fact, the lightiter step really

only provides one light per pass.

However, that shortcoming is fixed in the render manager branch. Not

sure if/why you need multiple lights, but if you're really adventurous

you could play around with the RM branch.
