To get the lumps to be separate from the trunk, I would suggest exporting it with the 'Group by' set to 'Hierarchy' and that you assign enough levels. For example, if you has a Trunk with lumps and Big Branches growing off the trunk, then I would set it to Level 1 or Level to 2 - 'Major Branches'. This will keep the trunk, lumps and branches separate. Depending on how you want it divided, you just count the generators and set the levels accordingly.
Thanks, Is there a reason that 0-All doesn't capture all of them?
0-All spits out a single mesh, but choosing 3 for a 3 generator mesh spits out all 3?
Grouping by hierarchy sets the level in the tree under which the tree will be split apart. For example, a level of 0 means the entire mesh in one group. A level of 1 means the trunks of the tree will each be in different groups with their children (in most cases of simple trees, this will be identical to level 0 since there is only one trunk). With a level of 2, the trunk will be in one group and then each major branch will be in a group with all of its children.
so the decorative geo (lumps etc) attached to a trunk would come out with a 2 - essentially the same as branches. The 0-All actually means everything in one shape, rather than all levels that exist in the tree. Is there any way to control what sits in each level - much like the way you can control the wind levels? as in these 4 nodes are in level 1 and these level 2.. this way i could control the grouping of the shapes for export.
