Tags not loaded properly from asset-bundle models. #46

Open shadowmage45 opened 6 years ago

shadowmage45 commented 6 years ago

Debug output from an asset-bundle based model, that should have the 'Airlock' tag on the 'Airlock' transform.

Apparently this is a known and long-standing issue with Unity and Asset Bundles (not specifically caused by KSP or TexturesUnlimited) --

https://answers.unity.com/questions/23862/tag-on-a-gameobject-which-is-loaded-as-an-assetbun.html

https://forum.unity.com/threads/my-tags-are-getting-changed-when-its-loaded-from-asset-bundle.466801/

https://forum.unity.com/threads/tags-and-assetbundles.132984/

It has been a problem since at least 2012, with no sign of resolution coming from the Unity devs.

Okay, so the solution is to ensure that your tag list in your Unity Editor exactly matches what is expected by KSP. Any mis-match in the ordering will result in the tags on the objects loaded from the asset-bundle being incorrect.

This is how you need to setup your tags in the Unity Editor in order to have them saved properly into the AssetBundles:

[Click and drag to move]

Which looks like this in the editor (click on the 'Add Tag' button, and make sure your list matches this exactly) :

With the above setup completed in your editor install, make sure to fix the tags on your models (they likely were changed when you updated the values in the tag manager), recompile and/or re-export your .smf models (recreate the prefab, and re-build the asset-bundles).

After the tags have been fixed in your editor install, and your asset-bundle models rebuilt, they should then load fine in KSP. (at least my test model loads properly with the above changes having been made, and the asset-bundle for it rebuilt)
