# How do I diffuse light that responds to the thickness of an object?

I have an image of a lampshade that I am trying to make a material shader for. I have a bulb inside that is a point light or I have also used a light bulb model with emission for cycles. I am trying to render in cycles to get a photo realistic render.

I can't go with emission because I need the subsurface to stay white corresponding with the subsurface image.

• Lampshades that are lit by an point light from the inside often benefit from some transmission value to allow the light to "pass" through the shade, which should respond to thickness the way you want. Jun 11 '20 at 2:31
• Hello :). Please add some reference image, so we know what exactly you're going for. Jun 11 '20 at 12:10
• I added a couple of images of a render and the shade I put together with translucency and sss Jun 12 '20 at 14:26
