Gta 4 Playerped.rpf Backup

The playerped.rpf backup is an essential safeguard for any GTA IV modder working with character models and ped textures. playerped.rpf contains the default NPC and player character files—models (.wft/.ydd), textures, metadata, and configuration—so losing or corrupting it can break animations, cause missing textures, or trigger crashes. Creating a timestamped backup before making edits ensures you can quickly revert to stock assets if a mod conflicts with game updates or other mods.

Short overview.


Start Page:
The program is able to work in both mm and inches.
iIt uses Splines to generate the Valve lift curve, with this approach it is fairly easy to copy any
measured Cam lift curve and then modify it or make new Cam design from scratch.
Splines aren’t as limited as the more common Polynomial curve approach and with Splines it’s easy to
design an asymmetric lift profile. With the adjustable 2 stage smoothing function it’s also easy to get
low Jerk values without compromising the lift curve.

Duration etc. Calc for up to 4 Cams:
Change the centerline and calculate directly the changes in opening, closing degrees, lift
at TDC and eg. 10 deg. before/after TDC etc.

Comparison Cam nr. 1 ( 2 and 3 ):
This Page takes its input from the lift data in mm/inch with 0.1, 1 ,2, 4 or 5 degree steps data in the left Window.
For Hand measured Cams there is the option to smooth the generated lift-velocity-accelleration and jerk data.

A complete reference to parts needed from eg. Ebay is supplied, as well as full schematics
to the wiring and firmware for the Arduino Uno board that controls the Steppermotor/Driver and the
Mitutoyo indicator.
Excluding the Mitutoyo indicator and its SPC cable, the price of parts from Ebay adds up
to just under 400 $ (December 2014)..

July 2020, Linear encoder indicator option included.


An example of a Cam measuring Machine made from the referenced parts ( + an aluminium
profile cut and milled, not supplied ) :
