Sweet tutorial!
Thank you for taking the time Pat!
Here's a screen capture of the above MacHD/Applications/Carrara5/Contents/MacOS/Data/Plants/
Info, for those of you who are visual like me...
Plus, I just found out that you have to QUIT out of the App to get the list to include your new model in the Plants List, otherwise it doesn't show up and kinda crashed Carrara on me.
