repro: https://playground.babylonjs.com/#92Y727#292 comment/uncomment line 39 which is the offset. Switch to 4.21, you’ll notice that a) the axes have changed ! b) no worries, simply edit line 39 to AIlabel.position.z = 0.4*100; Now, you’ll notice the motion of the AILabel is different from 5.27 …

repro: https://playground.babylonjs.com/#NRNBMM#533 Switch between 4.21 and latest. It seems that parenting and billboard mode has changed between 4.21 and 5.27. I guess the question is: what if I don’t want my child to be affected by the parent’s rotation while the child is in billboard mode? Is t…

My approach would be, to create a TransformNode inbetween (because you want offset and rotation), then set node as parent of small1. At last set node.position to absolutePosition of box. This might give results you want? PG: Babylon.js Playground Babylon.js playground is a live editor…

Thanks, there are indeed many workarounds/hacks. I dimly recall that when billboard mode was created, it was intentionally made to exclude some parent transforms. I fail to understand the application for the billboard in its current incarnation (other than some fringe use cases). Regardless, my reas…

This seems to be the reason: [image] BillboardMode rotation bug Bugs PR Fix billboard translation with parenting by CedricGuillemet · Pull Request #12984 · BabylonJS/Babylon.js · GitHub

I see now. I think there wasn’t a bug, @brightMoon use case could simply be implemented using an intermediate transform node: https://playground.babylonjs.com/#NRNBMM#534 @cedric I presume its too late to revert the PR ? Can we have a programmatic switch to bypass/turn off whatever was added ? Do w…

Adding a transform can also solve the problem. However, for my demonstration, parent scaling is just a bug for billboard. 5.27 Did fix the bug. After 5.24, the bug appeared https://github.com/BabylonJS/Babylon.js/releases/tag/5.24.0 https://github.com/BabylonJS/Babylon.js/pull/12984 Therefore, …

Lemme get your application right, you want to a) parent a plane to a cylinder, b) have the plane face the camera c) have the plane maintain its position and size when you scale the cylinder d) have the plane rotate around the y-axis when you rotate the cylinder and still face the camera ?

[image] phaselock: a) parent a plane to a cylinder, no, Cylinder and icon plane have the same parent, they are a whole. [image] phaselock: d) have the plane rotate around the y-axis when you rotate the cylinder and still face the camera ? Keep it always facing the camera

ok, so a picture is worth a thousand words: a) parent a plane to a transform node, parent a cylinder to same transform node? b) have the plane face the camera c) have the plane maintain its position and size when you scale the cylinder d) have the plane rotate around the y-axis when you rotate t…

[image] phaselock: d) have the plane rotate around the y-axis when you rotate the cylinder and still face the camera ? The cylinder does not rotate. The position of the cylinder does not change, but when the camera rotates, the plane always faces the camera
