Hi I’m considering OpenRNDR for my next project.
I wanted to ask if it supports multiple windows as I have not been able to find any examples.
For my usecase I would want to have a small control panel UI window on one screen and then the output on a secondary screen as a fullscreen window.
Is something like that possible with openRNDR? Could you point me to the right direction? Thank you 
Hi @joekhan! Welcome to the forum
I think the multi-window feature is available in openrndr 0.4.5-alpha2
You should get that version if you use the next-version branch of the openrndr-template.
There are at least two demos you can study under openrndr/openrndr-demos/src/main/kotlin at master · openrndr/openrndr · GitHub
Let me know if you try it! I still didn’t have time to give it a spin
Cheers!
This looks really promising thank you! Will try right away 
Seems to work pretty well but I’m facing an issue where the contents of the window shrinks to 1/4th of it when moving it to a secondary display. Is this perhaps a known issue on macOS? I am also able to reproduce the bug running the default template demo on master branch:
I hear that it might be related to mixed DPI and this probably needs some work. I’ll post more news when I have them
Meanwhile… is there any way to have the same DPI in both screens?
Hey there! Sorry about the late reply.
Yes, that’s what I’m doing for now
In macos display settings I can set the external display to be in the resolution marked as HiDPI and then things work fine
Off-topic but I’ve been watching your videos on shaders and they are extremely helpful! Hope you guys can make more in the future
I’m happy to hear that, thank you for letting us know! @Alessandro has been very busy with work lately and I hope he has time soon for some more conversations. Looking forward to it
Now there’s two demos for having a GUI on a separate window
(for now only available if you build orx yourself). Basically one only needs to replace GUI with WindowedGUI
