While you may use a meshlight as a deforming piece of geometry, deformation motion blur is not yet supported and could provide incorrect results.

Light filters do not currently work with mesh lights.


In creating a meshlight, you may see a material connected to it called PxrBlack. This material has no parameters and is designed to prevent the mesh from scattering light a second time from itself. This is done to provide something intuitive, not necessarily something physical.
