I have created a 3SM which attaches correctly in MicroStation and looks fine. When I export to LumenRT and then attach the 3SM in LumenRT it comes in at the wrong scale. It appears to be about 3 times to large. This appears to be the meter/US foot scaling difference.
This MicroStation screen capture shows the 3SM attached correctly along with it's properties and the GCS info.
(Note the scale factor of 0.30480)
The video below shows the attachment in LumenRT where the scale issue is obvious when compared to MS screenshot above.
(Please visit the site to view this video)
Is there a solution to this scale issue?
Additional observations about 3SM attachments in LumenRT:
Excessive flickering in the 3SM portion of the scene.
Orbit navigation of the scene becomes awkward unless your cursor is directly over non-3SM geometry.
It is very disappointing that the display of the cyclorama of distant hills goes away when the 3SM is attached.
Regards,
Ron
