I have Descartes for MicroStation 08.11.09.601 and Lumen RT installed with update 15.50.22.44. This is a STM file with picture wrapped:
1) Sometime the pictures is visible a bit
2) Sometime the pictures is not visible at all
3) stm file is moved every time it is exported
Please download the *.rar attached containing how to fix this issue. Then follow these instructions:
1) Close Microstation and LumenRT
2) Rename the folder C:\Program Files\e-on software\LumenRT 2015\LumenRT\Export\Microstation to Microstation_old
3) Unrar the enclosed rar archive (Microstation_patch.rar) and place the folder Microstation into the folder: C:\Program Files\e-on software\LumenRT 2015\LumenRT\Export
4) Restart Microstation and try exporting again
