Pivot Problem with Xfrog Plants
« on: December 29, 2014, 11:14:36 PM »

I met some problems with Xfrog Plants that have got some roots. When I open the original Max file everything seems to be allright. The pivot is well aligned to the end of the trunk. But when I merge or xref them into Max with Forest, they seem to fly above the ground. I think Forest uses the bottom of the bounding box and not the original pivot from the object. Even when I unhide the custom object it looks alright (see attached file).
Changing Z Offset in forest doesn`t help, because when rotating or scaling the trees, Forest will use the wrong pivot.
Am I doing something wrong? Or is this a known problem? Is there any workaround?

Hi, This is a known problem but has not easy solution:
XFrog plants are composed by several grouped objects. Since Forest requires a single mesh, these objects are attached together in the importing process. Once loaded, there is not reference of the previous pivot point.

This should be the procedure to fix these items:

1) Unhide and unfreeze the forest_templates layer (imported objects are stored here).
2) With the Forest object selected, use right click->Select Forest Custom Object (quad menu), to select the plant you want to modify.
3) Once selected, apply Group->Explode from the Max menu.
4) Align the pivot point correctly. Forest items will be updated automatically.
5) Freeze and hide the forest_templates layer.

Anyway, for next updates we'll check if we can implement an easier workaround. For example, that Geometry->Offset modifies the pivot point.
