Hinges, motors, and spokes have all been unaffected by these things since they were introduced.
- Not affected by transparency
- Not affected by global shadows
- Not affected by dynamic lighting
- Always appear on top of particles
Also, not pictured - Not affected by reflectance
- Not affected by materials
- Not affected by meshes
This is quite the laundry list of bugs and I’m assuming there’s a reason none of them have ever been fixed. Frankly these things would be ugly even if they worked; could we get a property to disable them from appearing? A boolean property in the lighting that disables them would be nice.
