Setup: Step by Step setup basics for HDT Physics Extension

This guide will get it working first. You can THEN install add-ons afterwards.

Install SKSE.

Required: Minimum v1.6.16.

Install a body with T/BBP compatibility.

T/BBP is REQUIRED. Well known bodies and their derivatives will clearly say in their title, features, or related documentation. If it doesn't say, assume that it isn't compatible and look for an alternative.

Install skeleton with BBP or TBBP compatibility.

Required. Start here if you need one. Most often, this will be an xp32 created skeleton. Others will say in their documentation.

Download the HDT plugin for SKSE.

Required: Go Home > Download section if you need it.

Install with a mod manager or open the zip into the Skyrim game directory.

If you're using a version older than v12-29:

1. Open the directory: Skyrim/data/SKSE/plugins/ (If this dir doesn't exist, create it. Go ahead, it's ok.)
2. Copy in the files hdtPhysicsExtensions.dll and hdtPhysicsExtensionsDefaultBBP.xml
3. v9-23 or earlier: Remove the date from the plugin dll filename so that it is now hdtPhysicsExtensions.dll.

Done.

Enjoy the show!
