Short description of error
Import does not acknowledge solid FALSE.
This bug is acknowledged in the code, but I didn't see a ticket for it.
Exact steps for others to reproduce the error
Import a shape with solid FALSE
Activate backface culling
Observe that the shape is not double-sided
Added subscriber: @Seth-Gold
Sample shape: solid.wrl
I have some code to implement this at https://github.com/Sgeo/blender-web3d-fixes. Had some trouble extracting just the relevant commits into a patch though.
But what I'm doing there is duplicating the mesh, flipping normals then joining. I don't know if that's appropriate. The exporter for solid=FALSE into X3D just checks material use_backface_culling.

Changed status from 'Needs Triage' to: 'Needs Developer To Reproduce'
It seems the code declares this as a limitation indeed. I would discuss this with the developers first before submitting a patch if it is not straight forward.
