Thank you for your answer,
The "hand painted/drawn" part really scare me, i'm really bad at drawing.
The effects i want to do are not destined to be in a game, but in an animation, do you think the "texture drawing" is required in this domain too ?
Indeed the "particular" plugin is really good for making trails (missiles, magic shots...) but how about the impact/buff/Aoe spells ...
You can see the effects in league of legends animations for example :
Rakan very cool thing
