I have one doubt. If delete one face in cube, the output of the verge3d is not same in the rendering output. It seems to be open in the side of cube. pls. tell me reason.
In Blender all objects double-sided, but in Verge3D not, because of optimization. If you want to get the same behaviour you need to set Render Side in Verge3D section of a material preferences to Double-Sided.
