Hey @Ritterbecks
After checking it out a bit more, and digging through some old forum questions, it kind of seems like this was a known bug at some point, that Post-Processing does weird things with reflections. This kind of makes sense, as the Post-Process Volume wouldn’t technically have access to the code that’s creating the reflection.
Have you looked into using Lumen to calculate the reflections? It comes with a bunch of features that support some pretty dynamic reflections.
I hope this can help!
