Alright. Alot of people whom use 3d Max and other softwares are telling me that my bakes need a cage file. I'm using Maya and there's nothing for cages in the autodesk knowledge for Maya. Could someone explain this? Bake.
I do some baking in Maya and some in xNormal. When I'm ready to move to XN, I like to pull a duplicate of the generated cage (+any tweaks I may have needed to do to it), and also export that as an obj. Back to the OP, the cage limits ray distance to keep bake times low. In other apps, the cage can also skew the casted ray…
The cage is around us, it surrounds us and binds us together.... Actually Maya will create one when envelope distance is set to anything higher than 0, should also check display options as seen here (mesh, envelope, both), you can even move it's verts around like a regular cage before bake!
