I am interested in Grease Pencil as a film industry standard for NPR. Now that Grease pencil can use 3d lights is there a possibility to incorporate real time normal mapping to the grease pencil “Fill” tool. I believe this would be a great advantage to the 2d world whether it be 2d sprites for games or 2d charcater rigs. If this is a possibillity , are there any developers that would be interested in pursuing the integration of such a feature ? What sort of cost is involved and time frame?
