>>I would be curious if it is possible to achieve out-of-box in Persona, or would I need to write some supporting code first.
We’re working on making this easier. Currently it is difficult to do right out-of-box - i.e. spring blending. Our blending is set ranged from [0, 1].
Once we iron out some workflow issues, we’re going to post tutorial. But this won’t be happening at the first tutorial.
>>In my case I have different weapons, and on top of that dual wielding different weapons (where it make sense, although nothing wrong with Rambo style two M92 in each hand). I would be really interested in more detailed explanation about the setup used in Fortnite.
I asked Laurent to write “tricks and tips” for this kind of issues, but basically fortnite has one pose animation per weapon type. I think you can try layer both hand to be different animation depending but you might need some additive trick to make it look different between one weapon vs dual.
>> my characters have lots of attachments (at least 6 weapon attachments, shoulders, random things like pouches
For character attachment, it is easier if you just use spring controller than adding real physics. Usually looks more stable and better.
I’ll send this to Laurent and Matthew for them to join.
