Babylon currently does not have Light probes, only ReflectionProbes - but they do not capture light.
Your best bet would be to use backed lightmap for static objects, and a procedural HDR reflectionTexture (I’m working on this, expect the first prototype soon) to light dynamic objects with PBRMaterial.
Otherwise, use StandardMaterial workflow with four kinds of Lights (but it has a limit of 9 lights for any scene/material) and procedural Shadows.
