Oh I forgot about this question! I figured it out a couple of weeks ago.
It went something like you explained.
I went into “Content->ThirdPersonBP->Blueprints” and opened “ThirdPersonGameMode” and changed the “Default Pawn Class” to “Revenant Player Character”
Then I went into the “Content->ParagonRevenant->Characters->Heroes->Revenant” and opened RevenantPlayerCharacter" and on the components tab highlight “Mesh”
Over on the right now see Mesh->Skeletal Mesh changed the skeletal mesh to the Revenant skin I want to use.
This gets you basic animation with a LMB attack (though no projectile/particle effects, just in Revenant’s case a recoil of his pistol), run and jump
It would be nice to figure out how to incorporate basic water interaction as well but for now that is enough.
Thanks! I guess I don’t have email notifications enabled. Apologies for taking so long to answer your quick reply.
