Hi, Planar reflections are working on 4.14.0 forward rendering somehow, but there is issues…
I have scene with “infinity mirror” (3 planar reflections close each other) and there is some problems…
I think somebody else also reported that planar reflections are not working on 4.14.1 (i haven’t updated yet to 4.14.1)
Make sure that you also enable planar reflections from material settings on Forward Rendering tab of your material behind planar plane.
