Dynamic Collision Adjustment

Have you ever tried sneaking to fit under some object and was disappointed that crouching does nothing? Have you also noticed that some modded creatures have badly scaled collision? This plugin aims to fix both.

This small plugin took a lot more time and effort than I expected. It features two main functionalities and a debug drawing function.

A giant with 2x scale in vanilla and with this plugin.

The character controller collision is a very simplistic shape that is used by living actors for collision, for pretty much all purposes - movement, projectiles, melee (with Precision, the actor's ragdoll collision is used for melee attack collisions instead). For races that do not have custom shapes inside their skeleton.nif, a shape (or three, for actors that aren't upright) is generated in runtime. This kind of shape is already resized using the actor scale correctly.

However, characters that do include custom shapes inside their skeleton.nif were previously unaffected by actor scale. Such races include adult playable races, dragons, giants, mammoths, trolls, frost atronachs and quite a few more.

This plugin fixes that issue, so mods that change the scale of actors using these skeletons will now have correct collision.

You can enable debug draws in the MCM if you have TrueHUD 1. 1. 8+ installed and marvel at how inaccurate the simple collision shapes really are. It's the reason why your arrows sometimes clip through the target's body, or hit when they shouldn't. I'm working on a plugin to change that.

In vanilla, the character controller collision shape is static, it does not change at all after it has been created. This means that even though you can visually see your character crouching when you sneak, the shape that actually collides with other objects is, disappointingly, the same size.

The mod detects the change in the actor's state and adjusts the shape when sneaking and swimming. The scale multipliers are configurable in the MCM. The relatively conservative 0. 75 scale multiplier was chosen as it's around the highest point that the character's head reaches during the sneak movement animation. Set it too low and you'll get clipping and camera collisions.

Both the player and other playable races are affected.

You will not be able to stop sneaking while crouching under an object. Only the normal functionality (pressing the toggle sneak button) is affected, this is intentional to avoid any
