This mod for the player and the NPC is the ability to climb obstacles, as well as climb over them like this,
as it was implemented in GTA San Andreas. Animations were taken from there, but with some changes.

Mod parameters can be changed in the reVC.ini file (created when reVC.exe is run).
The parameters are located in the [Climbing] category.

Installation:
1st method: Drop the contents of the game_folder into the game folder, confirm the replacement.
2nd method: If you have a reVC repository, transfer the contents of the source_code folder to the miami branch,
confirm the replacement and compile the project.

ReVC.exe config from game_folder: Release, win-x86-librw-d3d9-mss.
