Support for double sided mesh?

[freetoplay]

I tested a gltf model in the babylon sandbox that does not appear to be rendering double sided mesh (it's poking holes in the mesh). Is there a way to get around this issue?

You can duplicate your indices and reverse the order then update the vertexData or maybe disable backface culling

mat.backFaceCulling = false;

Disabling backface culling closes the holes inside of the mesh, but I still have an issue with random holes outside of the mesh, does anyone know of a possible solution for this?

The best option remains to set the glTF object's material to two-sided lightning mode

(or get the mesh material and set mesh.material.twoSidedLighting = true)

Side question, might this be good for semi-transparent closed bodies (like a cube), or is face ordering the only way out?

Unfortunately face ordering is still the best option (or using alpha premultiplied as well):
