light limit?

[illumine]

Is there a hard limit to the amount of lighting objects you can display as on in open gl. when I have more then nine nights each object from the ninth onwards does not come on.

Yes. I believe 8 is the maxImum number of lights visible in OpenGL.

Correct. Only the Renderworks modes can show more than 8 lights at a time.

In OpenGL, it wont always show the LAST 8 lights either, so its often best to turn off all but 8 lights when doing OpenGL renderings where light matters.

Keep in mind that the Heliodon counts as one as well, but ambient lighting should not. Light generated by glowing textures will not appear in OpenGL.

Thanks Jim for the clarification.

Is the '8 light limit' a limitation of OpenGL itself or of Vectorworks' implementation of OpenGL?

Hi,

A limit to the lights you see in open GL. Can you explain as the attached shows an open gl rendering with the lights turned on and there are more than 8 showing or do you mean something else??

Thanks Guys, appreciate the clarification.

I believe the limit is defined by the OpenGL implementation/version that we use.

It looks like you can see the 8 light objects, but not all of them are actually lit.

Oh, Yea now I see what the question related to.

You have a keen eye.
