Decals on scaled spheres

[Raitch]

I'm currently testing things with decals, however my entire stage in on a widen out sphere with `.scaling = new BABYLON.Vector3(25, 1, 25)`. But it seems as if decals are being treated like my sphere was never scaled; they wrap around a round sphere instead of the stretched one. I confirmed the behavior that if you select the box, the decal goes beneath the sphere: http://www.babylonjs-playground.com/#PSKRF#8

So basically do you have any suggestions on how I can tackle my issue? I have considered these approaches:
* Replace the sphere with a very similar heightMap. heightMaps can be scaled and decals respect that. However I would prefer not using heightMap for a sphere issue as of now.
* Maybe I need to make Babylon get that I scaled the sphere more than just setting .scaling?
* Try some wonky texture placing on sphere which I think will be a lot of work

Could be something I'm missing as of now which I would gladly get told.

Scaling can often cause problems (or least I have found it so). Rather than using scaling create your sphere using MeshBuilder.  This way your sphere is set at the correct sizes when created.

Not sure if I got my sizes right in the PG but you get the idea.

Nice! That made it work a whole lot better  is it possible to shrink that sphere only on X and Z on renderloop with the decal adjusting? Or do I need to generate a new sphere and decal each frame? Not sure if that's costly or not.
