Answered: Can I use 1 UV for 2 different meshes?
null
Hi,
I am trying to model a very simple model for a lamp, and I used 2 meshes for it: 1 mesh for the screen and one for the base. Both meshes are polygonal and completely separated from each other, but I have them grouped. I assigned 2 different ID colors with Quixel colors in Maya, and saved as obj.
I unwrapped the UVs for both meshes in a single square of the UV plane.
However, when I plug them into Quixel, the normals rotate oddly. This doesn't happen with any other model, and I did the Unity 5 (Azog) tutorial, so I assumed I could use the same square for multiple meshes, as it's done there.
Why is this? Can't I use a the same square for 2 different UVs? What am I doing wrong?

Could I see a video of this issue in action?
So I fixed it, turns out I was plugging the ID Color Map in on only one Mesh and not the other, so it read as them being one object. Plugged them back on and they work now! It also had something to do with the old Grey bug, but when I installed the Quixel Plug-In it fixed that too.
It was an unfortunate case of newbie errors + program bug.
