In the new version of Unity 3.4, unity announced that they would now support procedural materials (which is awesome, by the way). While I was researching it, I found this in the manual:
Allegorithmic's Substance Designer can be used to create Procedural Materials, but there are other applications (3D modeling apps, for example) that incorporate the Substance technology and work just as well with Unity.
I don't have Allegorithmic's substance designer and don't plan on buying it soon. What other applications or 3D modeling apps can make procedural materials that work in Unity?
Edit: I found that Allegorithmic has a program called Player. But it is on Windows only. I'm on mac.
