Maximum number of light sources in a model?

Recommended Posts

Is there a maximum number of light sources allowed in a model? I want to check shadowing in a display case, created by objects on shelves, from the display lighting at the top of the case.


To do this, I have created 36 duplicate light sources in the top of the case model to mimic the individual LED heads at 110mm centres. They are simple light sources, set at 100% output with an 80 degree spread & 30 degree beam.


No matter what I do, only the first 8-9 light sources will turn 'on' in the render - the others stubbornly refuse to show any light output even though they are identical & duplicated from the first fixture & have all of the same settings. I have tried rendering in variety of ways - the attached image is in OpenGL.


I have made similar renders before in VW2020 of other display cases, but have never had this issue before. Is there something I am missing?

Excellent- thank you. I thought it must have been a limit, but could not find that in VW help. Am rendering it now.

Yeah, what Kevin said. :-).

I always found it a bit arcane that in Open GL they limit the number of lights to 8.

Oh well.
