I used Adobe Illustrator to create PNG files of different CB strike points then shrunk to proper size within Resolve and moved to desired location. I can send you these PNGs if you want. I think my better approach would have been to create just the CB and cuetip dot as 2 files and place them depending them as desired.I recommend nothing....lol. I wanted something that I could use to overlay multiple predefined sources, and OBS seemed to have a decent following.
I have zero proficiency in anything audio/visual. Just enough to get by. I wouldn't mind sorting out how to do that CB striking point overlay you used as well.
