I am running into some odd stuff with a reflection probe.
It seems like the probe is not reflecting “True” data but is showing like a 90 or 180deg rotated and maybe scaled variance it seems like.
Maybe I am doing something wrong: https://playground.babylonjs.com/#G3H60K#44 line 781 is where the probe is created.
And every frame its renderlist is updated to be all objects minus the attached mesh.
It does not require a fix here, the sphere is not in the list so it is normal you do not see it. also it can not be in the list cause it represents the probe position so you won t see it.
In your case each element should have a probe with a different list.
Also in your pg the miror and the probes acts as infinite mirrors creating some weird artifacts but yes reflections on pure cubes are really hard to get right locally.
hmmmmm, honestly this might not be too hard to workout.
How intensive is it to update a reflection planes matrix?
In the case where I am trying to do a pyramid, I think I can get away with 2 planes for each pyramid. Only 2 faces at any one time could face the user, so if I have a correctly positioned plane and a isolated polygon that has the correct uv I could in fake it cheaply I am thinking?
