It does add BFC, but only for SimpleMaterials. When loading from WRL you will
have ChunkMaterials, which are not changed in that respect. Honeslty, I don't
know why not. Can you try adding the PolygonChunk part to the ChunkMaterial
case
in MakeTransparentGraphOp::applyTransparency?
In general transparency will have sorting issues on most non-trivial
geometries,
but try the BFC piece and if that doesn't work please put up a screenshot
somewhere.
Thanks
