Those aren't errors, but notifications that you need to update those parts of the game once you edit a map. You can update the shadows and ambient occlusion by clicking on the edit tab of the ribbon, then clicking the respective buttons on the left (calculate shadows, calculate ambient occlusion). Afterwards, be sure to save the level (it should be ctrl-s on linux, but I don't know for sure...)TurtleKing wrote:(Kubuntu 12.04 64bit & Nvidia 8600 GTS (may upgrade video card soon))
More detailed problem:
When trying to load an item from O2 or Object:
Nav mesh needs update
Baked shadow needs update
Ambient Occlusion needs update.
To recalculate the Nav Mesh, click on the pathfinding tab on the ribbon, and click on create nav mesh, then save nav mesh when it's done.
Just to be clear, all of these processes can take a while, so don't think that it has crashed while waiting on it.
