Hi gang! I found an older CSG/Godrays demo that once worked, but now doesn't. http://playground.babylonjs.com/#UUXLX#9
It looks like something is wrong with the godrays texture (the base64 image on the plane inside the rotating cylinder).
I was going to combine this scene... with a skull loader, to see if I could help @ancientholiday with a "CSG on imported mesh" challenge.
Advice welcome! Thanks!
(Hey Ancient... if you read this, be sure your skull is set updatable=true.)
Ok, bye.
