Hi!
I've created an iModel (.i.dgn format) from adgn containing only a STM and 2 attached rasters. Raster are draped to STM as you can see in the capture:
But when I open the iModel in Navigator the draped image has dissapeared:
I've tested both with "Keep Original" and "Reduce Size" in Raster Settings
OpenRail 10.03.03.18
Navigator 08.11.09.713
Any ideas?
