I've also downloaded and have quickly browsed a couple tutorials, but no real progress yet. Keen to get into it. The Renderman shelf showed up empty after I installed, and the forums say to "delete your prefs --> yay that fixed it". But I'm not keen to trash my prefs, so I'm wondering if anyone has an intact Renderman shelf .mel file they'd be interested in sharing.
Initial impression, I like it. Still working thru the differences between REYES and RIS And pros and cons of each. Also realized there is going to be a steep learning curve when I looked at things like render passes, not to mention the rib files.
@stwert, will the mel file from a mac installation work?
