(Forgive if this has been asked.)
I have uploaded 4 ship designs to the Steam workshop. Two of the designs are black in the Steam display (no image). I had to upload images and change the title adding "Click to see image." The other ships look fine. The possible difference: The designs that don't have an image include a lot of custom parts I created. Is this why the base images are black?
Speaking of custom parts, is there a way to upload those parts yet?
