Enlighten gi does not respect light layer setting

Since point light and spot light shadow are not supported for indirect bounce when using enlighten, I try to use light layer to avoid indirect light leaking but it does not work.

I setup several rooms and assign different light layers on them. Each room has spotlights setup with corresponding light layers and disabled shadow. The direct lighting works fine. Spotlights only illuminate their corresponding room. However, the indirect lighting still leaks to neighbor rooms.

I know apv dynamic gi is coming, but I heard that it has light leaking problem on indoor scene. Is it possible to for unity to fix enlighten for the time being before there is a working solution for indoor dynamic gi?

This is a known deficiency, and one that I am afraid is very unlikely to be fixed, as it isn’t trivial, and the Enlighten integration is very much nearing the end of its life.
