This is a total replacement mega mod that basically, turns your Sniper into a Spyper, and your Spy into a Sny. Almost all traces of their old identities are completely removed.
Every wearable item is fixed.
Every necessary sound is replaced.
Every necessary HUD texture is replaced.
A grand total of two thousand five hundred and twenty two files are replaced. I have no idea what possessed me to make this, but I did, so here you go.
Sny also comes with a custom Disguise Kit taunt and class select animation since he doesn't have a cigarette. A version of Spyper without Sniper's glasses is included in the download for those who would prefer to not have them on. To use it you'll have to manually insert it into the VPK. There are also files and instructions for only installing one of the characters instead of both. Instructions for doing both of these things are included.
Item fixes do not contain LOD's, normally this isn't a big deal but since there are so many item fixes, if your computer is really crappy, you may get a performance decrease.
The Festive Tree and TF2VRH no longer utilize jigglebones. Couldn't get them to work for some reason, sorry. All other jiggles are intact.
Items that cover the face have custom made flexes, but like all other flexed items, they are glitchy and do not work right sometimes. The Dapper Disguise no longer has facial flexes, but it does not clip with mouth movements.
The voice packs for this mod have been meticulously crafted to suit the new characters. Spyper will act like a Sniper, Sny will act like a Spy. It isn't a case of simple renamed files. The voice pack was very carefully made to take into account all cases of their responses, and includes a large number of custom-made lines, that all sound natural and have lip-syncing. If you choose to only install one of the characters and their voice pack, certain Sniper/Spy domination lines may not make sense since they are designed to account for the other class being replaced as well.
If you find issues with the mod, feel free to inform me, with as many files as there are, I probably messed at least 1 thing up.
Also it's worth nothing that this mod is 100% compatible with the TF2 Texture Improvement Project, and I highly recommend it. No stock texture files are overridden, UV map and model edits handle all the fixes.
