I have an extremely poly-heavy scene that I have broken up into many different chunks, then I xref'ed the whole thing back together. In the main file (not xref'ed) I have placed 4 Forests that use 4 different 'include splines' and several vrayproxies. All of the splines and vrayproxies are loaded directly in the scene. Nothing associated with the forest is xref'ed. So... I xref in all the buildings, then created the forests - everything is okay. I save the file, then open it and the forest objects are mis-aligned to the include splines. If I detach some of the xrefs, resave, then close and re-open the file, the forests look okay again. Then I have to re-attach the xrefs and render. It doesn't seem to be a problem with any one xref in particular. I have 7 xrefs. If I delete any two of them the forest works fine. Any idea what is happening?
I am using win7, max 2008, vray 1.5 sp4a, and Forest Pro 3.3.1
