Reflection Probe Lighting mode popup menu disabled in Mesh Renderer

I’m trying to create indoor reflection probes in 2017.3.1p4 for a scene which has both indoor and outdoor aspects. The rendering mode is Deferred. To do this, I need to be able to select “Blend Probes” as this excludes the outdoor skybox, which I don’t want to see in indoor reflections.

However, the popup menu in the Mesh Renderer component is disabled. It has the value “Simple”, which definitely isn’t what I need.

How do I enable this menu so I can select “Blend Probes”?

I should add that Edit/Project Settings/Graphics has blending enabled:

You found any answer to that? :smile: I have the same question

Deferred rendering is the reason why you can’t change it: Unity Issue Tracker - [ReflectionProbes] Disable reflection probes choices in mesh renderer for deferred rendering
