Thanks for all the added information.
It was not a hard critic towards you, but there has been quite a few work related requests in the past, that ended up as ‘just do the work for (almost) free and shut up it’s good for your portfolio’.
So when someone posts a work request that has only a gmail account, color me very skeptical.
Or battle scarred, as I have dealt with this more than I can count in my 3D career.
But if you’re going to do this with Blender, props to you and I wish you all the success in what seems a very ambitious production. There are some very smart cookies on this forum in various parts of the pipeline (I’ve done my fair share in that area myself), so I’m sure a lot of talent can be found here.
Good luck .
edit: With all the quick advances in Unreal, a mixed pipeline would be a very interesting thing to look into. Or have a look at what Ian Hubert is doiing with Eevee in Blender.
