I came to ask instructions on implementing custom "parsers", I did not look closely in an IDE, but by glancing on GH I'm not sure how the loaders resolve to one type or another. Could you give pointers?

Thanks, I just started using three-d and I love its flexibility

EDIT: Found the entry:

three-d-asset/src/io.rs

Lines 155 to 183 in 0850040

	impl Deserialize for crate::Scene {
	fn deserialize(path: impl AsRef<Path>, raw_assets: &mut RawAssets) -> Result<Self> {
	let path = raw_assets.match_path(path.as_ref())?;
	match path.extension().map(|e| e.to_str().unwrap()).unwrap_or("") {
	"gltf" | "glb" => {
	#[cfg(not(feature = "gltf"))]
	return Err(Error::FeatureMissing("gltf".to_string()));
	#[cfg(feature = "gltf")]
	gltf::deserialize_gltf(raw_assets, &path)
	}
	"obj" => {
	#[cfg(not(feature = "obj"))]
	return Err(Error::FeatureMissing("obj".to_string()));
	#[cfg(feature = "obj")]
	obj::deserialize_obj(raw_assets, &path)
	}
	"pcd" => {
	#[cfg(not(feature = "pcd"))]
	return Err(Error::FeatureMissing("pcd".to_string()));
	#[cfg(feature = "pcd")]
	pcd::deserialize_pcd(raw_assets, &path)
	}
	_ => Err(Error::FailedDeserialize(path.to_str().unwrap().to_string())),
	}
	}
	}

Just not 100% sure about the wasm part but it seems to be handled at an higher level, anyhow I'll give it a go

Thank you for the kind words 🙏 Sounds great you want to give it a go and yes, you found the right spot. And I think you should not worry too much about wasm. Of course there are some limitations on web (no threads for example) but if it works on native, it should be straight forward to get it to work on web.

Nice I got a very basic version working (no object transforms, no materials) using the fbxcel crate.
I just found Amient's implementation: https://github.com/AmbientRun/Ambient/tree/main/crates/model_import/src/fbx
It looks quite feature complete and I will take inspiration from it for the materials this weekend! I'll propose a PR then or early next week

Super nice 💪 Sounds like a good plan! 🙂
