For some reason, in the mechanism view, my models are just solid black, making it very difficult to work with. The graphics are there in the scene and the actual graphics gallery, but otherwise it is completely black. Is there a fix for this?
Go to the Options panel and check if "Default Lights" are on, this should help. Don't forget to turn them off when you're done since the default lights add to whatever light sources you put in a scene!
If this doesn't work, could be a graphics card issue. Make sure you're running a supported type and that the computer is using it (some computers default to another card).
That was it! I had previously turned it all the way to 0% for testing out some underwater camera mechanics. Thank you!
