This is extremely useful, especially when you're tired of playing as the basic cop models. There is so much customization following using the GTA V Online ped. You will need the Simple Trainer for this.

What I've done is to use my GTA Character in Rockstar Editor Mode, saved the outfit with the trainer and then loaded it in Singleplayer normally. Works quite fine.

That's not really helpful at all, since the OP has already shown how to do it, plus I gave an alternative.

I didn't think of that. I'll have to try that. I guess with the other way it'd be easier to start from scratch. Especially if you want to use a female ped.

Didn't think many people that use lSPD:FR knew about it. Every video I watch is always the same peds over and over. Thought I'd lend a helping hand with this discovery.
