I’m not sure what to call this. Rhino is actually the only program I’ve seen that has this:
So 3dsMax has the reverse. You model something super detailed, then model a simplified version of it, and then look to the other object to get detail. The simplified object has to be unwrapped properly.
What the Rhino one here is doing, well for one it’s over multiple NURBS surfaces so it’s Super awesome, is projecting to an object that’s been unwrapped. It then takes those UV’s and applies them.
It’s basically the same as camera mapping, only, it’s from one object to another. You can have one object Crazy detailed. Then you model a simplified version, UV unwrap that. Then tell the complicated model to project from it’s normals to get it’s UV position. It’s pretty genius. Similar to camera mapping, your complicated object, needs to have pretty tight, even tessellation or you get some odd results. But this isn’t for game models. These meshes are crazy tight. It would be Terrible to try and UV unwrap them.
I don’t know what they might be calling, if it’s something that exists at all in Blender.
Anyone have an idea? It is a really powerful tool, and it’s useful both for going simple to complex, or complex to simple. You can also do multiple objects to a single object, which is also useful. Doing mapping this way also helps keep your UV unwrap placement sized appropriately, which is something I’ve noticed automatic mapping methods usually fall a little short with.
