Thanks. I didn’t realize there was a similar topic open already, i searched for “mesh distortion/warping” and similar wording but didn’t see anything related at first glance.
P.S: I “think” i have some sort of workaround… but it doesn’t cover up for rotating the parent mesh before adding the children (like in the example you have mentioned)
Making a new transformNode, placing it in the childs position, then parenting the child to the anchor, and the anchor to the node seems to work somehow. Rotating the child seems to work fine, rotating the anchor warps the shape as usual.
P.S 2: I tried resetting the parent rotation to zero, then adding the children, then setting it back to its original state. It seems to work.
