Please How to add google earth or google map into LumenRT? I have my model in IFC file I want upload it into LumenRT?
only things that can be converted to polygons are handled by LumenRT. So I would suggest to you if it is the case, to drape the image on a terrain.
If you encounter any other issue, there are here some suggestions given by David on this matter:
Note that there is defect in that combination: Microstation CE up 4 + LumenRT CE up 1 the draped image is not exported, but fixed in the next release of LumenRT CE up 2
I hope this helps
