Hi DarkGreyMatter,

Please have a look here,

I have two spheres included, just in case. Images tell a little bit, but typically they don't give the whole story. I like project files. They work, or they don't.

The Transmission Slider in the Light makes the difference.

.
Please share for future questions a project file. Thank you.

If you think that should be done with the Exclude list, please check with Tech Support.

Please note that the following Monday is a holiday in some countries, so Tech Support might not be fully staffed.

All the best
