"reflectionTexture.boundingBoxPosition" not working for Cubemap Box


I am trying to adjust the boundingBoxPosition of a reflection texture applied on a skybox without sucess!
In this PG https://playground.babylonjs.com/#RNASML#48 there are two meshes, the skybox and a ground, both uses the same reflection texture but if you disable and enable “the Local Cubemap Mode” in the buttom you see that the ground change its boundingBoxPosition but the skybox do not, somebody knows why?


One is in SKYBOX_MODE and therefore do not support the local cube map adjustements.

Ok, thanks @sebavan
