Hello @NikDeLion

Did you try with the jetway sample in the SDK ?
I could not reproduce the issue.

Send us your project and we will investigate.

Hello @Boris

I have the same issue. Everything builds without errors but the simobject doesn’t spawn. When placed as a normal scenery object is does load.

It only happens with a simobject I just now tried to make on 1.8.10.0. Simobjects I created previously load, spawn, and work without issue.

As normal Scenery object

As Sim Object (Nothing loads only the small cube and Gizmo)


Previously created SimObject also loads fine

I have sent the SimObject setup in Private Content

It seems that, at some point, you forgot to change the model folder name in sim.cfg :

It should be set to LOWS_HANGAR_H5

You will need to remove the simobject from the scene, rebuild the project and add it again to see the changes.

Oh my… I feel very stupid now…

I am sorry for this. I did indeed change all the model names after receiving it from my model artist (as I always do) and must have missed that like you said. I am sorry to have wasted your time and thank you for the hint! I probably didn’t pay too much more attention after I saw this bug report and thought it must be related! Apologies.

I can confirm it does work now. Thank you for the quick help!

Best,
Michael

I’ll be able to share the files in an unspecified amount of time/days. I installed the latest SDK from SU5.1, the SimObjects build worked fine, and I was able to spawn them in the scene. However, if I completely delete the package, install SDK 1.7.2, and build the same package again, my library isn’t in the SimObjects library selection list. I can’t figure out why, but I’ve never encountered this before. I usually export GLTFs from 3ds max 2026
