Succubus can have tails and wings, but not the others I haven't set in they nodes for that, I haven't considered it necessary with those characters.
Cloaks only are shown with dynamic-playable races (Humans, dwarves, elves, etc).
They can't ride. However, any of those models include animations, all use supermodels for that, so riding versions could be made if you change the supermodel reference.
Head aligned VFX. maybe, I haven't tried that, I don't know too much about VFX. However they have human scale, so VFX for humans probably work with them...
Thanks for you quickly answer.
Please, correct me if I'm wrong
I assume, is not posible to do dynamical appearences of this quality.
For that, I propose to do a face and hair less versions of those models. To put on it a head aligned VFX with custom faces, hairs and ears by script.
And do the supermodel thing you was mentioned.
In the future, others custom content makers, can do, with your permision, texture alterations to make armor and clothes variations.
Thanks.
