I’m trying to load the helmet GLTF and replace each Mesh with its “thick” Wireframe equivalent but I end up with an unexpected 90 degree pitch in the end. [2022-11-10 13_48_42-Edit fiddle - JSFiddle - Code Playground - Brave] I traverse the node tree twice. On the first pass I run updateWorldMatri…

Fixed by attaching the new node first and then copying the position and quaternion. parent.attach(child) child.position.copy(sibling.position) child.quaternion.copy(sibling.quaternion) Treat Object3D.matrixWorld as a read-only value.

If you want to add an object of lines to the object it was made from (a base object), then why do you apply .worldMatrix of the base object to it?

I want to attach the object of lines to the parent of the base object, not to the base object itself. I’m trying to replace the original base object with a wireframe version of itself.

Seems I succeeded with it here :thinking: LDraw-like edges - #42 by prisoner849

Thank you. I’ll check it out.

have u checked the axis? make sure u are using y axis instead of the z axis

Setting matrixWorld and attaching to parent overwrites the rotations with [I]
