I have two new tropical plants for you. The first is an amazing palm tree, with a sculpted trunk, and alpha fronds with no alpha sort bug issues. It comes with a scripted sun following shadow which rotates, grows and shrinks in accordance with the SL day, and flexes naturally in windlight to match the natural movement of the tree. This is the ultimate in realism, and can be seen in action at Baby Monkey in Dindrane Elfor, next door to Gardens by Gonkers.
I also have a New Zealand tree fern with a sculpted trunk and realistic windlight reactive fronds.
Both of these plants need to be seen to be believed!
