Also, I’m new to Babylon, especially on the graphics end of it, so please be patient with me if able. What I’m trying to do is make a “cutout” of a mesh that …

Hello, You could achieve this using CSG2 like so: https://playground.babylonjs.com/#XTO3Z8#2 For simple meshes like this it is a fine solution. For more complex meshes you might want to csg subtract only once, select those vertices of the hole and just update their positions in a drag observable (…

Thank you for the quick reply! That certainly could work, but I might look into the shader option too; I’m using pretty simple and thin meshes.

Keeping an original (non-hole) mesh as CSG2, then the hole-maker mesh create and convert to CSG2 can be very quick. [image] Spherical (double) Wedge with CSG2. Reusable class, fast update clapper_boardDemos and projects Maybe this is final, unless someone sees…
