Limited Fixture # that can be rendered.

Recommended Posts

Spotlight Open GL Rendering.   Colleague and I working together and it seems that we are at the Fixture limit of what can be rendered.  I have never seen this before.

Situation:  10 Color Chorus 12s  in plot,  5 (blue light) are high shooting down, 5 (red light) at ground shooting up.    All are focused and correctly oriented.  Only 8 are rendering.  Visualization palette shows all are on. 

Symptom:  As some fixtures are turned off (via Visualization or Edit Light) the non rendered fixtures start rendering.    In any combination there appears to a be a max limit of 8 visible renders. 


Any ideas?

The limit for OpenGL rendering is 8 lights.  Use Fast Renderworks instead.

"OpenGL renders up to eight lights in a drawing; additional ambient light, directional, point, or spot lights have no effect. Custom, area, and linear lights can be added."
