Reflection artifacts with multiple reflection captures

When using multiple reflection captures, artifacts in the form of squares appear over my scene (See above). These reflections also seem to flicker.

I doubt this is due to my capture setup, as the same artifacts appear when loading up Epic’s Reflections project. Could be a bug?

If it helps, here is my setup:

Using an iMac
OS: macOS Sierra 10.12.1
GPU: NVIDIA GeForce GT 750 M

I would test using OpenGL instead of Metal for rendering, however I don’t know how to change it (Or even if you can)

Hi CraftedCart,

I just submitted a ticket for this that you can track here: Unreal Engine Issues and Bug Tracker (UE-39865)

This looks to be a visual artifact that happens with any overlapping. Hopefully we can resolve this soon.
