Apologies, My earlier post was a little confusing. Thanks for the clarification request Paul. To clarify - each part of the trees can be adjusted (trunk, limbs, branches & leaves). However, they cannot be keyframed for animation. Ringo is right - you can use bones to make the tree move in the wind but that won't help if you want the tree to grow out of the ground and sprout leaves instead. Zenstar's Tree Druid can be animated/keyframed but I don't know if they'll be porting it to Carrara since Carrara now has it's own tree generator. I've used Tree Druid - the Carrara plug-in, not the stand alone - for years. I haven't spoken to Mike Pogue recently though so I don't know for sure. So what's the difference between Carrara's tree's and Tree Druids plug-in trees? This biggest is animation obviously. That's a function that I hope the will bring to Carrara at some point. Also, Tree Druid (TD) allows you to create a tree by season. In the fall it even creates leaves on the ground - the plug in version. In Carrara you need to always tell it what size and how many leaves you want. Here is where I'm really impressed with Carrara trees though. It has a tremendous amount of options that the plug-in TD does not. In fact, the advanced options are formidable. You can control everything, spiraling of leaves, leaf count etc. The image above shows the advanced tree options. Don't be overwhelmed by the advanced tree interface though. The standard tree interface will get you decent trees fast.
