Down Light issue

Hi there,

Hope someone may be able to help with an issue I seem to have with blackbody emitters in lights.
I've modelled, in Rhino, a light can within which is a sphere that has a blackbody emitter assigned to it.
I always seem to get light coming through the can, hitting the ceiling.

Sorry if this isn't the right place to post this question.
My first post! :)

Thank you
JBOctane

Please, always share at least a screenshot, to better explain your issue.
Probably you are having issues with the direction of the normals of the emitting polygons.

Thanks Beppe,

Wasn't sure how to do that but I think I've worked it out now.
Hope this works!

Thank you

Are you using an IES file?
If yes, check the projection node, and share a screenshot, thanks.
