Noise from light/emissive material

[chinglong]

Hi,
When I use the light/emissive material, that have a bit noise on surface, How can I solve it?

Don't use an emissive material as your light source. It is meant to be used for things like tv's or backlit buttons... not light sources. For that you should use point/area/IES lights.

Unfortunately, you will most likely still get some noise, for which you can use Photoshop:

Btw, can I ask why you have a glass lampshade inside a metal one?
