BoundingBox is correct now. But positionGizmo mesh has some problems,PG: Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

Not, it’s not a bug. Gizmo is attached to a node that has a negative scaling component. To preserve the orthogonal nature of the gizmo, it must be oriented that way.

My understanding is the gizmo mesh always oriented to positive scaling direction. I test it on blender and other 3D editor.It always oriented to positive scaling direction.

I’ve added a check for this particular case: Do not use determinant when preserving scaling BabylonJS:master ← CedricGuillemet:rootScalingFromDeterminant opened 09:55AM - 20 Apr 22 UTC (UTC) …

Thanks for your hard work!I will test it as soon as possible when PG lastest branch merge the PR.

It works,thanks for your hard work!

But i think that it is hardly to understand that when i rotate the mesh over Math.PI and the rotate degree becomes (angle - 180). I test it in other 3D editor.Because the rotate angle has direction.Clockwise is positive or so on.So the rotation gizmo behavior should add or reduce in one rotate dire…

angles are in the range[-pi…+pi] but you can accumulate the delta that is accessible here: BabylonJS/Babylon.js/blob/145041ad8cc1e4a59c49d483fff6320b4b4bfc11/packages/dev/core/src/Gizmos/planeRotationGizmo.ts#L51 /** * The maximu…

Gizmo use tmpParent but do not preserve scaling sign

Can we allow all type node to updateGizmoRotationToMatchAttachedMesh.Because we allow all type node attach to boundingBoxGizmo.But we has a warning.
