Hi there,

To begin with, I'm no expert modder and no expert in the CK. What I want to be able to do is revert a couple of the perk trees of a particular mod (ie. block and marksmanship) back to their vanilla, untouched state. Another mod I use has edited those trees and I'd prefer to use those. Of course I can simply load that mod after the one I want to edit and tree changes will be overwritten, but for various reasons I want load the mod that Im editing after the other mod to avoid other complications. I'd like to edit this particular mod so that the perk tree changes are removed and restored to vanilla but not touch anything else so that when I load it after the other mod no perk trees will be overwritten.

I know basically how to get to the perk trees in the Creation Kit but how can I revert them somehow, or import/export those particular values from vanilla skyrim?

Thanks in advance

There are two ways I would know how to do this:
1) Duplicate the mod with everything you want, ignoring what you don't. Load the mod you want to duplicate, but not as the active mod - you will make a new active mod with the changes you want. Then, edit everything that is in the mod that you want to keep. Then, when you save, those edits will be in your new mod. If you don't edit the perk tree, it won't get saved in your new mod. This would be a pita.

2) Go to File | Data to load the mod you want, but instead of just clicking the OK button, select the mod you want and click the Details button. From here, you can see the records that make up the mod. You can now delete the entries you don't want to load. When you delete, it actually flags the record to be ignored when loading, so delete all the perk tree entries. After you load the mod with all the perk tree entries ignored, save it again and they're gone. This is how I would do it. The only challenge is figuring out which records to delete.

Hey Sollar,

Thanks for the tip and the link. I'll give that second method a go I think. Baby steps

You're welcome. That's the route I'd go too.

TIP: I would suggest making lots of backups along the way. Save and reload your "test" plugin often as ignoring one wrong record could cause errors.
