Culling is enabled by default in Qt Quick 3D.

However, due to culling some models cannot be rendered properly.

Attached files are a FBX model of an automotive wheel and an application showing its QQ3D conversion result.

"culling_enabled.png" is rendered with default QQ3D and "culling_disabled.png" is rendered with customized QQ3D in which culling is disabled by default.

I am not sure this is the problem of QQ3D or not.

Possible solutions that I come up to mind are,

1. Disable culling by default
2. Fix meshes at conversion
3. Fix models by modeling tool (blender or similar)
4. Any other solutions?

What will be the best solution?
