Multiple light problem, material iteration, light limit

[robert_sasu]

Hi,

I am working on an air trafic simulator which uses Ogre 1.7.4 as a rendering engine.
Is there any light limit when using programmable shader ? I know there is a limit of the constant buffer and the calculations per shader type, so because of this I am using 16 lights and per-pixel-shading.
But I would want to see more than 16 lights on. I tried to set MaxLights to 128 (for instance) and use iteration 1 per_n_lights 16, but there are still just 16 visible lights on, even if there are 30 created on the scene.
After 16 lights if I set a next one to visible, one of the currently visible will go off.
I tried to use scene_blend add, but the result is the same.

Am I missing something ?

Thanks,
Robert

Check OGRE_MAX_SIMULTANEOUS_LIGHTS in OgreConfig.h
The default is 8.

Note that the complexity of checking lights becomes O( N*M ) where N is up to OGRE_MAX_SIMULTANEOUS_LIGHTS, and M the number of entities in the scene.
