transform Controls center not align pivot

The transformControls was not developed to support a pivot point. You should create your own modified control based on the original transformControls.

Globally overriding.updateMatrix like that seems like a potential source of hard to find/fix bugs? If you need to pivot around a different origin, just add a Group or Object3D above the object: So instead of: scene->[ mesh ] scene->[ pivot->[ mesh ] ] You can use .attach instead of .add t…

I’ve tried to do this, but it’s not easy to use, I have multiple scenes, a scene rendering helper, a scene rendering object, using attah makes my scene tree and hierarchy messy, etc

@manthrax I think your solution is the best Do you think it’s okay to implement it this way so that you don’t have any problems related to hierarchy? function attachTransformControls(target: Mesh): void { const originalParent = pivotHelper.parent; // remove the pivotHelper from the old target…

Maybe you add these few lines of code, switch between use, scale, rotate, and pan to manipulate the model multiple times, and you will find a lot of bugs [image] document.addEventListener(‘keydown’, () => { if (control.mode == ‘translate’) { control.mode = ‘rotate’; } else if (control.mode == …

@agargaro You can’t find it by using panning, rotating, and zooming alone, so you can use it in combination

Have you looked at : https://threejs.org/docs/#examples/en/controls/TransformControls.setSpace You may need to set to controls.setSpace(‘local’) ?

I corrected some things in the example, however, the attach method has this limitation (from doc): Note: This method does not support scene graphs having non-uniformly-scaled nodes(s). So if you scale the objects uniformly, this should work. [image] three.ez - TransformControls 2 - Sta…

What should I do if I assign an anchor/pivot point to an object, and the TransformControls are not updated synchronously?
