I appended the object from the copy of the original, as it wasn’t rendering in that file, I thought appending into a new file might help.
All I did was add a two simple materials, and a couple of material indexes. I’m going to try to re-create the problem, but if it’s something “obvious” to a more experienced blender, I’d love to know what the problem is.
I’ve actually never (intentionally) used the outliner-render flag
I only recently discovered this handy button too. In some ways it’s better than using up layers for controlling visibility of things like the proxy objects I use to block out animation curves, walk cycles and such.
Yeah, that’s a new feature. You can toggle visibility and selectability there too, so if you have a problem in the future finding or selecting something, remember to look there!
