Whenever I try to load the Stone Presets from FP, I get a MAXScript error:
Warning : Can't find object "" in the source scene
After this warning, Forest gets populated with a bunch of Geometry entries but none of the imported geometry gets tied to those entries... and the materials are not loaded onto the geometry.
I tried going into the presets to check for bad scripts or if one of the XML/json files pointed to an object that doesn't exist, but I could not find anything that stuck out. This issue
