Did you set that Gray as transparent in OBS for that layer? If so, try 48,48,48 as that was the best Gray we found for transparency.

We would love to see people like you make some videos to show case the software. We wanted to make a new one for launch, but our time has been put 100% into development. What did you have in mind? If you're around later in the evening, we should be around to talk if you want.
