Hi!

I'm probably just blind, the documentation is a little unclear in the VolumeData section. I'm searching
for a way to obtain the RayLight* from a BaseObject* that has been defined in my shader plugin
via link-field, something like this:

BaseObject* light = bc->GetLink(MYSHADER_LIGHTSOURCE, doc);
LONG index = **vd- >GetLightObjectIndex(light); // This is what I search for**
RayLight* ray = vd->GetLight(index);

Is it possible and I just couldn't find it in the docs?

Thank you!
-Niklas

EDIT: Corrected RayObject to RayLight.

Ah, I see there's the GetObj() method. Do I have to iterator over all available RayObject's to find the
RayObject associated with the light in the scene?

EDIT: Ok, I think RayObject's are not the light objects..

You can get each light with GetLight() then check BaseObject* RayLight::link against the light link pointer in your shader.

Thank you, Yannick. This works fine.
