Lighting limits with p3d_LightSourceParameters

@Alexander_krack

can these node inputs be in the form of structures?

I haven’t done it myself, but based on the list of GLSL inputs, it looks like something like that should work.

And searching the forum, I found this post:

Lights inputs in GLSL shaders

OK, I just checked in support for custom light shader inputs. You can now do something like this (just a hacked-up test shader, don’t take too many lessons from this): light = PointLight('abc') # Or Spotlight, or DirectionalLight light.setColor(...) light_path = render.attachNewNode(light) render.setShaderInput("customLight", light_path) // Custom light shader input, works on all light types except AmbientLight uniform gl_LightSourceParameters customLight; uniform struct { // Sum of all am…

The post is old, so things may have changed, but it looks like it may have the information that you’re looking for.

coming back to this, I want to have as much flexibility as possible, and I think a flexible number of active lights is the range of 32 - 50 lights or even possibly more if its doable.

If that’s the number of lights that you think that your project calls for, then it seems to me that it’s worth having that number of lights!
