Penetration-bounce system AE

An F4SE plugin that adds penetration and bounce, no patches required.

No compatibility, no pellets unencrypted, but can be customized if needed.

This mod adds projectile penetration and ricochet behavior based on damage, ammo type, and surface material.

The penetration depth calculation formula is as follows:

If the projectile penetrates, the resulting projectile retains only residual energy, depending on the fraction of its maximum penetration depth.

The bounce test is divided into two stages: penetration depth = total damage / 2 × ammo multiplier × material multiplierremaining power ratio = 1 - (actual travel distance / maximum penetration depth)

Angle priority ejection

energy based rebound

Current operating sequence:

Influence

Angle priority bounce check

If there is no trigger, perform a penetration test

If penetration fails, or angle-priority rebound has priority, make an energy reflection roll

Finish

The ricochet was blocked on approaching frontal impact. In fact, hits within 35 degrees of a frontal impact will not rebound.

Laser behavior configurable:

Ammo when isLaser=true is treated as laser ammo.

Laser ammo can only bounce off materials with isMetal = true.

Fusion Cell and Fusion Core ammo in the current version do not have the hard-coded vanilla auto-marking. If you want to treat them as laser ammo, you can add isLaser=true to the ammo bounce configuration.

Angle-priority bounce uses ammo angle scaling and material critical angle.

Energy-based bounce utilization:

Material category

material rebound loss

Ammo loss multiplier

Current bounce count

impact angle

Current material category factors:

Crispness = 0.7

Yield = 0.9

Unyielding = 1.35

Fluid = 1.6

Noricochette = invalidate the bounce

Energy-based bouncing uses this residual energy model:

This is a game experience heuristic, not a realistic ballistics simulation. Final balance still depends on in-game testing.

How to configure

Reading format for all ammunition and material configuration files:

Data/F4SE/Plugins/PenetrationSystem folder

Global settings are read from Data

/F4SE/Plugins/PenetrationSystem.ini

Example:

How to turn off bouncing completely

Set in Data/F4SE/Plugins/PenetrationSystem.ini:

This globally disables all bounce behavior while maintaining penetration.

How to reduce bounce

You can reduce bounce globally, both per ammo and per material, without disabling the entire system.

To reduce bounce globally: remaining energy = total damage - 20 × material resistance × ammo lossMultiplier × angle factor[AmmoMult]

Add BaseDrain to PenetrationSystem.ini

To reduce the bounce of certain ammo:

Lower the Angle Exponent to make Angle Priority Bounce more difficult to trigger.

Increased loss multiplier to make energy-based bounces lose more energy.

Set isLaser=false if you do not want the ammo to be treated as a laser ammo.
