Trying to create a frosted surface able to let lights to pass through it. Similar to a perspex panel with lights behind it, if that makes sense. Any idea on how to achieve that?
Thanks
Do you have any references images that are similar to your ideal outcome?
If your rendering to video, use an RT glass material, up its roughness, add an RT Glass refraction node, and finally a little bit of refinement to let the noise converge.
For real time, An easy way to do this is probably with a render layer with your glass object, use that as a mask for a blur. I’ve seen a similar trick for faking glass, render layer, get the normals, use that on bump map warp. i’ve included a quick example.
