Tnx Rich,
as using Thea for rendering then just (for testing) made really simple model of tree trunk as Instance base & used "ring" model as instance & basically that's it. Probably have to play with thickness of instances & have to create a better base model to get the proper shape of tree but otherwise does the job good enough.
My Q was pretty much for the interest if there's an easy way to do it in SU with any kind of plugins & from the point of getting smarter in SU. You're never too smart in SU, are you? π
Will try those suggestions You offered as well just out of curious. Thanks for that π
Cheers,
Mark
