Real First-Person Render Mod comes as a request by one of my flight simulator mod modelers. It’s a small client-side mod that renders the player’s body when in first-person. Although it may seem similar to the Improved First Person mod, RFPR is coded quite differently. It doesn’t require a coremod, and only uses one class file. This makes updating a snap, and allows it to easily be tweaked to work with any version. It also means that there are some inconsistencies; that’s the price you pay for simplicity.
It’s not 100% accurate and never will be, but it should give just a dash of realism for those who want it.
