shadow visibility does not work

Hi,
I have a plane with a blackbody emission material as a lightsource.
And a octane object tag assigned to the plane.
I always get a shadow from that plane casted on the ground
even if I turn off "Shadow visibility" (Camera visibility works as it should)
Latest Version 3.05.1
Any idear?
thanks
Mike

Same problem here. I would also like to know how i can exlude particluar objects from generating Shadows?

Hi guys,
which kernel are you using?
Maybe is the Ambient Occlusion effect?
p.s. latest version is v3.05.3

Hi Beppe,
I'm using PT
Lightplane is far away from the floor, so is don't think thats from AO.
It is a setup from an earlier project (maybe one year ago) and that has
worked before.
I'll try with 3.05.5 Version.
regards
Mike

Hi Beppe,
its not the shadow from another object, its the shadow from the plane itself
which has the emission material applied.

Putting a scene would be great to show expectations and what that is not working. I can't see anything wrong here with shadow visibility. But as i can see there's a problem with general visibility. Plugin ignores that objects when "general_visibility=0". It's about some optimisation for generating less meshes for case but this is not fine for emissive geometries.

Hi Ahmet,
thanks for your feedback!
" It's about some optimisation for generating less meshes for case but this is not fine for emissive geometries."
So what does this mean in my case?
I do need to find another solution to get rid of these shadows?
Because I need the reflections of that lightplanes on the object, but
not the shadows on the floor.
Old problem: We really need lights include/exclude option!
regards
Mike
