Alt + PrtScr together just captures the active window, so in your case the game window.Anyone out there knows a good program to take a screenshot inside RGPM games that works.
I already have BandCan and Flap, these two don't work for RPGM.
OBS is like the best thing ever for any type of screen capture. I used to use it to record kerbal space program and it was fantastic.
this way I already know there every Print has to open the editor to paste it but I solved it here with a program that I found and it worked cool.Alt + PrtScr together just captures the active window, so in your case the game window.
This one if you want to use it.The issue with the built-in Windows screenshoter is it doesn't automatically save screenshots, or at least I don't know how to turn this function on
