Run Vanda Engine. Make sure that you are in Prefab Mode (Mode | Prefab). Before you import the dae file, add a _LOD1 post-fix to your file name (for example camera_LOD1.dae). From the main menu of Vanda Engine, choose File | Import | External Scenes…. Locate the DAE file and click Open. Now Vanda Engine should report that new external scene imported successfully.
However, COLLADA cameras are not active by default. You should use Tools | Select Camera… menu to activate your desired camera.
Do it now and in new dialog box that appears, choose the name of your imported camera.
