A few days ago I saw this post: https://code.blender.org/2022/11/blender-apps/
It’s about using Blender as a standalone app. I thought it was a great idea and wanted to try it out.
I had a task to create a level editor for designers. The levels were for a puzzle game. This task was just what I needed to test the Blender apps.
Instead of building a complete editor in Unity, which would take a long time, I used the power of Blender.
The editor turned out well, the level designers are happy. It also went pretty fast, unfortunately there is no real documentation on how to build Blender apps. A lot of it is try and error.
I hope there will be documentation soon. The idea has a lot of potential.
