LocalDent 0.7 — Vehicle Deformation, Folding Panels & Dynamic Collision

ATTENTION: This mod was created entirely by ChatGPT 6 Astra. All I did was ask for what I wanted out of curiosity, and it did all the work. I did not expect it to work, but it works perfectly fine.

LocalDent adds localized body dents, folding hoods, and trunk lids to cars. The purpose is to add vanilla-friendly deformation to a rock-solid car body. Damage strength is based on collision impulse and vehicle mass. Version 0.5 also includes experimental front and rear collision compression. Deformation does not affect the vehicle handling.

Impacts create localized body dents, repeated crashes accumulate deformation, and hoods and trunk lids can fold roughly in the middle. The crushing effect may bring older driving games such as Carmageddon 2 to mind, while retaining the look of GTA SA's stock vehicles.

- Body deformation based on impact position, direction, and strength. It uses collision impulse and vehicle mass rather than health loss alone.
- Separate folding behavior for hoods and horizontal trunk lids, with configurable crease settings.
- Deformation for the player's vehicle and nearby NPCs, within approximately 100 meters by default. Nearby NPC-to-NPC crashes are processed too.
- Experimental front and rear collision compression, intended to reduce the “invisible bumper” effect after heavy crushing.
- INI configuration, Moderate and Strong presets available in the archive.

F7 restores the player's current vehicle's visible geometry and collision shape, but does not restore health or detached parts.

About collision deformation: the physical shape is an approximation; it does not follow every body polygon. In 0.5, physical compression affects the front and rear only. Roof and side collision remain unchanged. You can disable this feature in the .INI separately while keeping visible damage. This is not full soft-body physics.

Requires GTA SA 1.0 US and an ASI Loader. Copy LocalDent.asi and LocalDent.ini into the folder containing gta_sa.exe. No separate CLEO script is needed. Running it alongside VehDeform or other deformation mods is not recommended.

The mod is intended for stock vehicles. Collision deformation remains experimental. Compatibility with replacement models, graphics mods, and multiplayer has not been confirmed.

New in update 0.7:

• Added front and rear fender buckling.
• Added independent bending of front and rear doors.
• Wheels visually follow the deformed arches.
• Added the native headlight smash sound to rear lamps.
• Collision damage uses native front windscreen shattering instead of ejecting an entire pane.
• Rear glass breaks.
• Optimized deformation processing.

Version history

- 0.6.7 — separate intact/damaged panel shading, progressive boot fold onset

- 0.5 — experimental private front/rear collision compression and sphere refinement.
- 0.4.1 — separate glass included in deformation.
- 0.4 — nearby NPC vehicle support.
- 0.3 — hood and trunk lid folding.
- 0.2 — impulse/mass-based impact response and improved contact handling.
- 0.1.2 — geometry-copying fix following crashes in early builds.
