Skyrim Mod:Mod File Format/AVIF

< Mod / Skyrim: Skyrim Mod: File Formats: Mod File Format

The AVIF record is Actor Value information.

Most records are simple but the player skills have perk tree graphical information in them as well in field groups (below thick line repeats for each index).

CNAM is listed twice because it means something per group record and also at an individual record level (if no perk groupings). On the perk level, it is the INAM of the perk it connects to in the perk tree (line to). For example, Bullseye (INAM 7) in the Archery tree requires Quickshot OR Ranger, therefore both of those field groups have a CNAM field of 7.

Note: Smithing and Pickpocket are different because the initial CNAM does not match up (Pickpocket would start at Cutpurse) and the AVSK has different data throughout. It's possible the record-level CNAM has a different meaning than assumed.

Perk tree information:

  • This does not change prerequisites. Individual PERK records have CTDA for perk requirements that allow you to skip perks if removed.
  • 5 coordinates are given for each point along with any lines to other points.
