Haven’t found a general method to move the origin to the center of the object, and I need everyone’s help model.zip (1.4 MB) Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

You can use mesh.setPivotPoint(), see: [image] Pivots | Babylon.js Documentation Learn about pivots in Babylon.js.

The other solution is to create a new parent that will act as a pivot. After having center the object from the bounding box hierarchy. Overall, the topic has been discussed a number of times. Here are a few links that might be of interest to you: [image] Bring the Crane in from ou…

I think your plan is very good, but my model is to process the last-level nodes in multi-layer nodes. When processing according to the plan provided by you, it will deal with the situation where the model deviates far away. It is best to publish a more official document. Comprehensive case.

You can move the mesh to -BoundingBox.center and bake the current transformation to the vertices: Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

Cool. I’ve been trying this with a number of meshes I got from sketchfab. Though from the PG link above it didn’t work. I guess because the node is (may be) in fact the root. So I made an attempt here to translate this (better said, ‘combine this’) with the base I had implemented using ‘getHierarc…

[image] mawa: " Is any of this not necessary or even inappropriate? " I’m not sure what you mean, if you want to center based on the entire mesh hierarchy, then using getHierarchyBoundingVectors() seems appropriate.

I mean nothing in particular. I did multiple tests and I believe it works. I guess I just wanted to make sure that this is somehow ‘recommendable’.
