Thanks everybody for your reply.
Actually I’m not happy to give for free the project, beside the plugin, all the assets are all made by myself, even the 3d model, and most of the animation could be use in other project by them.
That’s the reason why I was asking about a reasonable compensation.
Anyway they should buy the plugin license by them self to work on the project.
But, replying to Mads, the client told me that I cannot work on foreign versions because are managed by another agency.
