Hello,
I'm using Maya 2015. Using Polygons. When I duplicate half of any mesh like a cube, the instance object becomes black because the normals are reversed.
1. Edit, Duplicate Special, Geometry type: Instance, Group under: Parent.
2. I try reversing the normals for the black object, but the half of the cube reverses to black since they are Instance objects.
How do I reverse the normals of an instance object without effecting the other half of the object?
Any help is appreciated.
Solved! Go to Solution.
Hi Neo
This looks like a new feature in Maya 2015 which shades back-facing polygons in black. I'm not sure if its intentional however as usually these features have an option to enable/disable them which I can't seem to find anywhere.
So although I don't know the proper solution to this yet (Only just installed Maya 2015) I do know that if you change your viewport renderer from "Viewport 2.0" to "Legacy High Quality Viewport" the problem goes away. This is a less-than-perfect solution however.
If anyone from Autodesk is able to provide a better answer/solution to this that'd be really helpful. It seems to me that this feature/bug, although potentially useful, does break a lot of other features in Maya (Like negative scales etc). Also since a lot of the rendering tools in Maya allow you to render back-faces, it is inconsistent and doesn't honour a lot of the rendering options like "Double Sided" for example.
Thanks

OK, so having done a little bit more research it turns out that this is actually an old viewport preference which defaults to being off in Maya 2015:
In your viewport menu simply go this this menu item:
Lighting > Two Sided Lighting
And the problem is fixed.
Thanks

not sure if y'all are still around but you just saved my life in 2020. I was having the same problem. I'm a beginner. thank you
