I have 30,000 reference files, coming from 3.5 Gbytes of i-model data. I need to get that into LumenRT. I have tried building up the scene files gradually, turning on references and exporting to LumenRT step at a time. I got a quarter of the data in before it started crashing LumenRT.
Are there any suggestions for getting large datasets into LumenRT.
It would work if the dataset could be converted to 3sm format. Unfortunately such converter is used only internally by Bentley.
LumenRT terrain is 4x4 km wide but there are some Bentley demos that long linear road project is imported in LumenRT but again it may be some special version.

This screen shot shows an export I made to LumenRT from MicroStation that is about 8.4x8.7 km (12 km diagonally).(LumenRT Update 14, nothing special)
Strange result. And how long is the edge of the overlapping grass block?
It varies depending on how large of an area you apply grass on. If I only apply to the narrow gravel shoulder it's about 3x3 feet. If I apply it to all medians, slopes, and gravel shoulder it is about 6x6 feet.
Apply grass only to gravel shoulder
Apply grass to gravel shoulders, medians & slopes
It also looks terrible on the slopes.
Thanks for this - we have an enhancement request in to fix grass on slopes. The issue has to do with normals coming from MS
Hi Ron,There is indeed a limitation about how large the grass-covered area can be, before artifacts appear.LumenRT uses a 4000x4000 texture to store information (altitude etc) for the entire area covered with grass.This means that if the grass-covered area is 4km wide, you will see 1-meter-wide squares.There is also an issue with slopes, that is also related to the texture mentioned above.The "stairs" effect can also appear on small areas, but it is amplified on larger areas.This is not due to the normals coming from MS.As Dave said, we have an enhancement request to get rid of these limitations.Regards,Alex
I read that grass was fixed in latest version but seems not.
