Heyyy, it's been a while since I've done anything! Better get back on track with a fully produced track with real recorders! As I mentioned in the description of the video, this has been laying around for a pretty dang long time. While I still think this track is way too silly for me to take 100% seriously, it still is pretty important to me, so I felt I needed to publish it and move on with it. Hope you'll enjoy!

I'm developing a Blender import script, but I've not been able to find source code or documentation of any kind for Will Kirby's LibLR2, which is used in the model viewer. I've done my research and reverse-engineered the model files to the point where I can do what the viewer can do, but I wouldn't want to reinvent the wheel any more if the work is already done and available. Edit: Here's the WIP script that imported the above mesh. It works with most models. It's for testing, so you're supposed to use it from the text editor. Change the strings at the bottom of the script to your own file locations. Image tutorial below. from struct import unpack from sys import argv from os.path import split, splitext, join import bpy, bmesh def readnulltermstring(input,skip=False): if type(input) in (str, bytes): #else it's a file object null = '\0' if type(input)==str else b'\0' return input[:input.index(null)] if null in input else input if skip: while 1: c = input.read(1) if not c or c == b'\0': return buildstring = bytearray() while 1: c = input.read(1) if not c or c == b'\0': return buildstring buildstring += c # All models use the .md2 extension, but the actual file format within is discernible by the first 4 bytes. # MDL2 and MDL1 are chunking formats, but MDL0 is not.

Again, other way around... Copy from Rocket Racer to Player One (or whichever player you want to replace). And copy, don't cut or delete the originals.
