I have attached in my *.dgn (whatever Microstation based software) multiple cells from this library: C:\ProgramData\e-onsoftware\LumenRT 2015\LumenRT Content\MicroStationLumenRT_Content.cel
When I export to LumenRT some cells are missed (characthers or plants or vehicles):
Option 1
Delete all the ~empty.lob files in the C:\ProgramData\e-onsoftware\LumenRT 2015\LumenRT Content\LumenRT folder and subfolders. Follow the below steps:
1. Go to the folder C:\ProgramData\e-onsoftware\LumenRT 2015\LumenRT Content\LumenRT
2. Do a search for *empty in the search bar:
3. Hit Control A to select all the file and then delete them
4. Now re-export and all should be fine
Option 2
1. Navigate to the folder C:\Program Files\e-on software\LumenRT 2015
2. Replace the LoadVOB.py file with the file attached
LumenRT_LoadVOB_Patch.zip
