Hi,
I am new in Babylon and I do not know how to solve this problem. I have data in .obj format from Blender and when I try to display them via BABYLON.SceneLoader.ImportMesh only one side of Mesh is visible (the other one is divided in to 2 triangles). I have tried function BABYLON.Mesh.DOUBLESIDE but I have not found way how to used it for imported Mesh. It worked for Mesh creation but not for import.
This (hidden) static method can transform a singled sided mesh geometry into a double sided geometry
It works at the VertexData level of any mesh, imported or not. The mesh is to be rebuilt from the new VertexData anyway (changed geometry :twice more vertices added)
