Features
-
[](V1. 1) Manual submerge, use the sneak key to submerge. Swim to the surface to clamp again. [/]
[]Adds sprint swimming for both perspectives[/]
[]Procedural turning for 3rd person character body and legs for smooth swimming, works with any animation replacer[/]
[]Procedural turning for 1st person hands while swimming, works with any animation replacer[/]
[]Adds the missing 1st person directional swimming animations and overhauls the idle[/]
[]Swim enter animations, from ground and falling for both perspectives[/]
[]NPCs can use the new animations[/]
Installation
-
[]Install a behavior patcher, Pandora or Nemesis (only one of them)[/]
[](v1. 1) Install SKSE & Address Library[/]
[]Be sure that you have a dedicated behavior output folder (check behavior engines' pages for their usage)[/]
[]Install the Mod[/]
[]Tick "Swimming Extensions" patch and run the patcher[/]
Requirements
-
[]Pandora or Nemesis. Choose one, not both[/]
[]SKSE & Address Library (v1. 1)[/]
Compatibility
-
[]Behavior & Animations -> All skyrim versions (SSE)[/]
[]Manual Submerge-> 1. 5. 97 to 1. 7. 104[/]
[]Compatible with Skyrim Water Inertia, and recommended[/]
[]Compatible with Simple Diving System[/]
[]Compatible with everything that doesn't edit the swimming behavior (underwater attacking mods should work)[/]
[]If you have a mod that slows you down underwater Skyrim might disable the sprinting-> Disable / configure the mod that makes you too slow underwater. Wade in water does work without patches, per my testing.[/]
[]PC head tracking has an optional patch to suppress the breathing sounds when fast swimming (only for the base mod, not others that add custom breathe sfx)[/]
[]Other sprint swimming mods will be redundant[/]
[]Animation replacers will work fine, HOWEVER since I added new animation states for 1st person (vanilla uses Idle animation for all swimming states), existing OAR based replacers may not directly work.[/]
