probably the error is happening somewhere around lines 273 and 318 in VRMExporterV0.js, when saving sparse accessor data im probably missing to set correctly 4 byte boundery

just tested 1558 and it seems like some with no atlas option selected are also producing this error, HOWEVER it is still able to load in hyperfy. (shown below is no atlas)

but the one that doesn't produce this error throws an error and won't load (shown below is with atlas)
