I am helping with #neuroscience research using #Unity3D for animal studies. Unity is powerful, and I have had no trouble getting a free educational license, but still, it is a license. Is anyone doing animal studies (3D #VR) with a license-free system like #Godot (#GodotEngine)? I would be interested in hearing about the pros and cons. Note that some of our applications require multiple external displays (at least four, ideally six) running at high frame rates (at least 120 Hz, ideally 240 Hz) showing enough 3D geometry that we need LOD management.
