Correct event before draw to match 2d projection with 3d space

Hi. I’m trying to achieve linkWithMesh behavior but for simple Vec3 point. (aka Control.moveToVector3). But i can’t find time where i have to update control positions.

I’ve tried every observes like before/afterRender and so on. But everything renders with frame delay. Example with rotating camera. Small dots (2d) have to be in the same place as spheres

Have you tried

camera.onAfterCheckInputsObservable ?

It doesn’t trigger at all

can you repro in the PG?
