rendering selected theatrical fixtures and skp import

Recommended Posts

Hello - 
Issue 1: when rendering ETC colorsource PARs an image of black circles renders (see below with a wide round lens). Almost as if the LED diodes were projecting shadows.

Issue 2: when rendering light on an imported skp model, it appears to have self-illuminating features, rather than accepting the light from fixtures. Can this be altered?

Any assistance would be greatly appreciated.

The lens geometry within the fixture is filled with solid pale blue colour and when you render it in any mode with the ambient light turned off you will see the black circular shapes of the geometry lit by possible bounce from the floor. To see the pale blue of the lens, you need to turn on ambient light. However that would defeat the purpose of turning on your lighting devices. To get these to glow without ambient light you need to follow the instructions in this video. 


(EDIT: You can skip the earlier steps about making the lens geometry because this fixture already has it for you.)


What Sketchup is doing is taking the pale blue colour built in to the lens and lighting it.
