[Substace Designer 2017.2.2] UV set 0 doesn't exist [SOLVED]

daniellooartist

Issue: Backing special maps in Substance Designer results in the following error. "Baking failed (Normal Map from Mesh)

UV set 0 doesn't exist"

Steps Taken To Isolate problem

-Baking generic cube exported from Maya 2016.5 Ext2 in FBX format. Issue occurs with all objects
-Settings in image below
-Switched "Set distance width" from cage to values. No difference
-Switched between material to Sub-mesh
-Switched on/off the option of "use low as the high definition"
-Checked Maya to see if I accidentally created a new UV set somehow. I did not. UV is on default UV set


Steps Taken To Resolve
-Using documentation: https://support.allegorithmic.com/documentation/display/SDDOC/Bakers
-Googled the living crap out of it.

Solution
-Combined your low poly mesh to one mesh object before creating your cage.

Can we get the mesh?

Sure thing. It's just a regular cube though.

Update: I was able to get the generic cube to bake out with no error after I created a new package. Same thing with the mesh data I intend to use. The only thing I did differently was creating a new graph with the bit depth parent dependant as opposed to 16bit but that doesn't make sense to me. Huh, weird. Closing this out. Thank you for your help.

Update: After playing with it a bit, I have determined the cause was that Substance designer can not bake multiple meshes at once on a low poly or cage. High poly can remain multiple meshes. Before creating the cage, ensure your mesh is all one combined object. Odd because I remember the Youtube video baked out a helmet with multiple mesh's. I dunno.
