I've created a tree with wind animation in speedtree and exported to Alembic format, 10 seconds worth. This imports to 3ds max 2014 without problem via the Exorcotex Alembic importer. When adding the tree as a custom object it works fine, the animation is carried into itoo forest, great! However a problem encountered is that when imported the tree is made up of seperate objects all animating in sync so when ungrouped I can only selected, branches or leaves seperately. If I group the tree then add as a custom object itoo forest shows nothing. If I ungroup and pick the leaves for example it works fine. I had this working yesterday which is the frustrating thing. The tree is over 1mil in polygons and the Alembic (abc) file is 4.5 GIG. Not sure if this is causing the problem, file limit in iforest? I've upped all the display limits and toggles different settings to get them to show, no luck. Not sure if this is supported as this is Alembic but an interesting problem to address hopefully as the results would be sublime if this worked.
Hope someone can advise.
