GLTF, culling and winding order

I’ve been playing around with Gltf files in Monogame.

They can be loaded by using the fbx loader (doesn’t work with assimp for some reason).

My default rasterizer state is to cull counter clockwise (same as the monogame default).

However, from reading, it seems as though gltf used counterclockwise winding order by default, so in theory I I shouldn’t see parts of the model (or any of it).

Does the default fbx loader swap the winding order to be clockwise so models show with the default rasterizeratate?

Separately, I tried toggling the swapwindingorder option in the pipeline tool, but that has no effect on the gltf file I tried.does that option work?
