[darglein]

Thanks for reporting this issue. It appears that the trailing / breaks the file name processing. I will try to fix this issue now. In the mean time use:

./build/bin/adop_viewer --scene_dir scenes/tt_lighthouse

[darglein]

This issue should be fixed with 51fbf9e1e0acbe2fc051ad353a45480181c3e394

Please verify if all scenes are now working on your system.

[creiser]

Yes, works now with a trailing / as well.
