In the screenshot we see:
- Static Geometry (including clones)
- DynamicGrounds (green wireframe things)
- Collision nodes (blue spheres)
- Markers (purple dots and boxes, sometimes the marker is also blue, which can be enemy spawns)
- Beacons, such as
--- Crates (brown cubes, seemingly always unstacked?)
--- Helmets (gray things) Golden helmets (yellow things)
--- Blue, dark green and purple spheres (?)
- Unidentified objects (including the cyan/white circles at the spawn area), see image below
