Asset Bundle Build Error

[OutOfCage]

Hi, LG Team. Last month, we change the version from 2019.07 release to 2019.11. We check many functions work but sometimes build map or vehicle asset bundles error. This is the error log.

In my code, Assets/Scripts/Editor/Build.cs:219 is L264 in current code.

                    RunAssetBundleBuild(assetBundlesLocation, environments.ToList(), vehicles.ToList());

Assets/Scripts/Editor/Build.cs:400 is L447.

                            archive.CommitUpdate();

What cause this issue? How can I avoid this issue?

Thanks.

Hi, I thing you forget adding new assets files to required folder. For example, if you are building new Environment Asset bundle you should place all asset files on specific folder in */Assets/External/Environments/EnvironmentName/Models/EnvironmentName/*****. For example lets say we have terrain on our new environment and we have applied texture assets on terrain. In such cases, we mush place all these texture assets, trees or whatever in mentioned folder.

Another reason may cause build error should be the error on scripts such as importing not project libraries. Hope this helps.

SeymurSm is correct, all map/vehicle specific assets should be in the external object's subfolder to be built into bundles correctly. Otherwise it may detect no textures to build which will fail to add when we construct our vehicle/map bundles.

That said, you mention this only happens sometimes. Are you able to correctly build a vehicle then fail the next time? Or are some of your vehicles building and some not?

@SeymurSm @mark-gerow-lge Thanks for help. Some of my maps or vehicle build fail and their asset files are not all placed on specific folder. I will check this issue.
