Pls see the release notes at https://render.otoy.com/forum/viewtopic.php?f=45&t=56137 to see the version you need for 4k monitor support.Not sure if you've had time to work on it, but as of 3.7.0.85 the UI scaling is still broken. I can't see the text on the "OK" and "Cancel" (I assume that's what they say) buttons on the bottom of the menus, making the plugin useless to me. I'm running a 4K display on Windows 10 with 150% zoom on text.
