I’m wondering if it is possible to create a semitransparent object behind which certain assigned objects are clipped. This would create a kind of boolean effect. It seems to me that the stencil buffer might be involved based on this related [playground example](https://playground.babylonjs.com/#XU86GQ#2). The example does almost the opposite of what I want, but still the concept is there.

Could someone direct me to relevant documentation on achieving this?

Hello and welcome on the forum !!!

I am having some issues to understand exactly what you are trying to achieve ☹ could you try to draw it maybe ?

This might help redirecting to some relevant documentation but you might look for clipplanes: [Use clip planes - Babylon.js Documentation](https://doc.babylonjs.com/how_to/clip_planes)

It’s been an age, but clip planes were the answer. Thanks sebavan!
