Short description of error
Blender 2.8 send a error message (No valid cage object), when i am using a cage object to texture baking. Same objects are working fine in Blender 2.79
Exact steps for others to reproduce the error
I have 3 .obj files (low res, High res and Cage). I make the import of each one object, i create a new texture, i create material nodes, i select the objects in an appropriate order, i change the "type baking" to "normal", i check cage box and select cage object. I make click on "bake" button. Blender 2.80 cannot make the baking. It saying that the cage object it is invalid.
Same process it is working in Blender 2.79.
