Hmmmm.. There's a mod for PD3 for replacing each individual loot type with it's own bag (i.e. Money vs. cocaine vs paintings would all have their own bags), which I could modify with pones.

Likewise, in PD2 there's a mod that randomly replaces individual thrown bags with a different pony every time they're thrown.
I'm... unsure if a dynamic bag switching mod like the PD2 one can work currently in Payday 3. Would probably have to be in solo mode only.
(The PD2 mod requires lua code to be run, and so only works if you're the host of the lobby. And also it breaks loot bags for anyone in the lobby without the mod. But of course, PD3 is online only, with no lobby hosts...)

@lotuscookie hopefully they fix that

cause i had a lot of good mods for payday 2 that worked for the entire game cause i always hosted

@lotuscookie

someone posted a bag mod on nexus that is a single file and it looks like the person made it so the 20+ images replace all the bags randomly
