Hi, what is the licensing for any assets created with this tool?
Hi, never thought about that, tbh. I have no intent on putting any extra license on the output. So if you own the appropriate rights to the input sprites, you should be fine. Hope this helps.
Thanks for the response!
This is amazing! A paid version with undo/redo and manual input of values (instead of just drag sliders) would be very useful!
Thanks alot! Stay tuned for upcoming features :)
I can finally stop using skypaint!
Wow, never heard of skypaint before, this looks really antique. But it shares the same idea :)
BRO WHAT
HOW IS THAT EVEN FREE?
This is a gem software
Thank you so much for this one, it's extremely useful
Wait, where's the donate button? Please let me buy you a coffee at least
Thanks alot! Love to see your results in action!
I made it 1 year ago thanks to your tool, exactly what I needed back then :)
Great! Not sure how you placed the stars but I’m thinking about a particle option that might help in such cases :) Thanks for sharing!
Unable to display.
What binary did you try and what exactly happened? Is a logfile created? Thanks!
I can only see the background color, but I can select and move the material with the mouse.Win10.
Did you try to open the demo project from skytool_demo_project.zip via File -> Load Project?
Yes, it doesn't work.
did you use the most recent version 0.0.3?
