I waited like 5 days & still no response. Whats going on?

So i only had few addon peds installed, but what comes to mind is a character model file that my friend sent to me. He said its from a game that i don't even know what its from, not even my friend know what game is this from.

Heres the download link if you want to port it into the game.

Let me know if its ported.

@Oskar Ok thanks!

Edit: Still appears as a normal model & not the custom one...

@GTATerminal I replaced the .ydr & .ytd files with this: https://www.gta5-mods.com/weapons/razorback-bo3 & the .rpf file is in the patchday3ng folder

I was wanted to have a custom weapon mod in the game but when i replace it, its not appearing as a custom weapon model. Instead it only appears as a normal model. Can someone help me how to fix this?
