Bugs

Here’s my PG : https://playground.babylonjs.com/#C77SMH#1

I don’t understand why there’s not only a circular hole in the ground…

Could you help me ?

Thanks in advance,

Boris

Using thin planes with CSG is usually not a good idea as the algorithm doesn’t deal with them very well, you could use a thin box instead: Babylon.js Playground (babylonjs.com)

Ok, thanks a lot @carolhmj

I don’t know if this bug could be an issue in the Github code, maybe only to write in the documentation that the CSG functions don’t deal very well with the plane.
