Autodesk just released a new Hotfix for Navisworks (all flavors) and it fixes/resolves the following issues…
- Problems resulting from operations that involve clicking in the first column of the Clash results grid, such as collapsing/expanding groups, dragging clashes and resizing columns.
- Issues with material and transparency inconsistency when importing FBX files.
- Issues with the automatic selection of the correct Rendering engine (Presenter or Autodesk)
Note: it is not necessary to have installed Navisworks 2014 Service Pack 1 before installing this hotfix
