Having problems with STLExport on heroforge.com

object.boneTransform( b, vB );
object.boneTransform( c, vC );

skinIndex.fromBufferAttribute( geometry.attributes.skinIndex, index );
skinWeight.fromBufferAttribute( geometry.attributes.skinWeight, index );

to this:

skinIndex.fromBufferAttribute( geometry.attributes.skinIndex0, index );
skinWeight.fromBufferAttribute( geometry.attributes.skinWeight0, index );

Because when logging the object, that was the name of the attribute
