One of the weaknesses of "Hero" project is the preproduction in backgrounds, the one month of preprpduction
was spent almost in the story, animatic, animation tests and characters designs, no much time for backgrounds.
So now that looks like the grease pencil tool is working pretty well (It´s not just Hero, the Grease Pencil, development itself
is a huge time consuming but is the main goal of this project) and the animation is on track, I have time to give some love to backgrounds and now
we have two new collaborators in the team, Miguel Gomez Selva and Yanco G. Apesteguia to help in this task.
The most of the backgrounds are in 3D with a 2D look and the challenge is find a seamless integration between 2D and 3D elements.
We are trying different approaches like, different types of modeling, lighting, flat texture paint, even vertex colors.
Here you can see some tests about this process.
