Tutorial for setting up trees and bushes

Hi,

It would be great if we could have a tutorial on settings up trees and bushes in the same style as this:
http://docs.cryengine.com/display/SDKDOC2/Tree+and+Bush+Setup#TreeandBushSetup-SetupinMaya

It’s written for cryengine and I’ve tried to translate this into Lumberyard, but its not that simple. Even using the sample files the Maya Lumberyard plugin detects that its ‘old data’ and tries to covert it (which seems to mean dumping all the assets in one group).

If anyone can take a look at the link above and translate it for lumberyard that would be great. Or if there are tutorials out there for setting up trees and bushes with bending proxies etc then let me know.

Thanks
