NewtonWorldRayCast and two sided polygons

[Adversus]

Does this only works with single sided polygons?

Is there away to change this or is it a major performance hit?

I have a lot of collision mesh data that I use and I don't really want to have to go back checking and re-exporting.

Thanks,
Adversus.

Nothing in newton works on double sided faces, and that cannot be changed in newton.
adding the faces twice with the winding inverted will only make part o fteh collision system malfuntion, so save yourself time and agravation by not doing that.

Newton simple does not work with double side faces it is designed to work with object that has volumes.

Unfornatly you will have to extrude double side faces to make it have a volume, doing that will make a nice collision behavior and Raycast will work
