DashLoader currently crashes trying to initialize a Transformation because it passes in the standard 3 Vec3f's, when Porting Lib makes Minecraft expect 4. I narrowed it down to ItemTransformMixin, and I believe that's what's causing it because it introduces another non-nullable variable for initialization.

Cause: net.minecraft.client.render.model.json.Transformation.<init>(org.joml.Vector3f,org.joml.Vector3f,org.joml.Vector3f,org.joml.Vector3f)Suggestion: Check if the constructor holds all of the fields.

Object Stacktrace:
	in Transformation_<@DataNullablenull>
	at field thirdPersonLeftHand in DashModelTransformation_<@DataNullablenull>
	at field transformation in DashBasicBakedModel

dashloader is discontinued, this won't be fixed

Marking the field as nullable would probably make it not crash, but dashloader would probably not deserialize extended transformations properly. I would need to look into how dashloader works to add actual compat.
