How to flip PolygonMeshBuilder extrusion direction ?


Recommended Posts

Hi everyone,

I am using the PolygonMeshBuilder to extrude a 2D shape with holes.
However, the `build` function extrudes the shape down by default... but I want it to extrude up :(....

Is there a way to switch the extrusion direction when building the mesh ?

For now I am flipping the mesh manually as I did not found another way.

mesh.scaling.y *= -1;

Here is the playground: http://www.babylonjs-playground.com/#1ZAXRO#0
