Unsupported Nu file

[Eraea]

Hi, looking for help regarding this format of nu files
here is an error log for trying to read the mesh
╭───────────────────────┄ Mesh ┄────────────────────┄
┆
┆ 0: Error: no variants matched at 0x18...
┆ ╭───────────────────────┄ V8 ┄────────────────────┄
┆ ┆
┆ ┆ 0: Error: no variants matched at 0x3a8
┆ ┆ Unexpected value for enum: 2
┆ ┆ 1: While parsing field 'usage' in AttributeV8
┆ ┆ at ssbh_lib\src\formats\mesh.rs:81
┆ ┆ 2: While parsing field 'attributes' in MeshObject

┆ ┆ 3: While parsing field 'objects' in MeshInner

┆ ┆ 4: While parsing field 'self_0' in Mesh::V8
┆ ┆ at ssbh_lib\src\formats\mesh.rs:23
┆ ┆
┆ ╰─────────────────────────────────────────────────┄

and here are sample files
https://www.mediafire.com/file/7pdv3dgtpejj39u/nu_samples.7z/file

the nu files are stored within folders inside DIR_2 per hash folder (excuse the formatting, this has been extracted by guess work since the compressed archive was proprietary and no directory names could be taken)

The backtrace is showing an error with attribute parsing for the legacy mesh format. Mesh version 1.8 wasn't used much for Smash Ultimate, so you may need to add additional enum variants. I would fork ssbh_lib and then add variants like Unk2 = 2 until the errors go away.

ssbh_lib/ssbh_lib/src/formats/mesh.rs

Lines 362 to 368 in 211414d

	pub enum AttributeUsageV8 {
	Position = 0,
	Normal = 1,
	Tangent = 3,
	TextureCoordinate = 4,
	ColorSet = 8,
	}

@Eraea Hello, that's amazing! You successfully unzipped the fhm2d file and have the folder format. Regarding the model data you're trying to load, it's an older version, requiring some adjustments to numshb and nusktb, among other things. I've designated the format as VS2.
I've been working on this for over two years. If you're interested or want to take it one step further, could I get in touch? Thank you very much.

Please post here if you find anything @cotemi. I would like to support all file versions if possible. Updating ssbh_lib makes it easy to add support in ssbh_data_py to update the blender addon or make a new addon in the future. ssbucarlos/smash-ultimate-blender#248
