Help With Livery for Newbie

Hi, I’m starting to have a play with creating some of my own liveries and I am
unable to build the package receiving the following errors in the console:
AssetBuilder | Could not find a valid simobject in
black’. Does it have one of [aircraft.cfg / sim.cfg / container.cfg] and does
it reference the correct model folder(s)? PackageBuilder | Failed to spawn
lister for asset group aircraft-c152-livery-black (type SimObject) (package:
scpcomputers-aircraft-c152-livery-black) Project:

I’ve followed the tutorial in the SDK and run the LiveryAircraft sample, even
creating a customised livery in there and that works. SDK Version: 0.20.5 Any
help would be appreciated. Thank you

Hi @StevePer63 , To create and build a livery via the project editor, you must
reference a valid simobject (the aircraft gltf and xml in the model folder).
If this is not the case, you will see this error. We will update the
documentation. As a workaround, you can always decide to create a manual
package for your livery without any valid simobject in it but this will
require the help of 3rdps tools especially to generate the layout and manifest
files. Regards, Boris
