OK. Found the solve on this, though it seems to be a bit of a bug that it is happening. I’ve got a shadow catcher floor layer separate from my reflection floor. The shadow floor layer’s reflection intensity was 0%, but when I turned that layer off, the offending reflection went away. It was the “appear in reflection” setting on the shadow floor that was causing the issue and turning that setting to off has solved the problem. So now I’m wondering, if the shadow floor setting for reflection intensity was 0%, why was it creating any reflection at all.
This seems like a bug to me.
Anyway, thanks for trying Todd and I’d love to hear if you have a solid reason for why this was happening.
