@aszabo314 @krauthaufen @hyazinthh We see this in other applications as well, thank you @gpaar.

EDIT: also related aardvark-platform/aardvark-concepts#1 (comment) and aardvark-community/assimp-net@ac5a7f8

EDIT 2: actually this is also related #68

given all that, upgrading assimp is imo the only way to go

[haraldsteinlechner]

@gpaar The current development version got rid of this problem temporary (new build of external lib), but we we need to come back to this issue again since the object loading lib is rather outdated. anyways - chances are good that with installing https://www.microsoft.com/de-at/download/details.aspx?id=30679 your current problem goes away. if not, and running pro3d on this machine is urgend, we can create a fresh build out ouf development for that purpose - or we wait for the next release which will fix it definitely.

[gpaar]

Thx - I installed the 30679 but no remedy. It's not immediately urgent for me as I'm now using the scale bar feature which is sufficient for my current needs. Nevertheless in the forthcoming delivery it shall be clean if it's being deployed to a larger community. Thanks!

[haraldsteinlechner]

new assimp build, also needed by #68 fixes this one. currently we are discussing the release plan...

[haraldsteinlechner]

seems that this one was fixed in pro3d 4.0. if you experience problems, please reopen again
