Este post es una traducción del original escrito en Julio del 2012 en el blog de Xuan Prada.
Estos son los puntos principales de un curso que impartí hace poco acerca del texturizado en proyectos de cine VFX.
En el curso utilizamos diferentes assets de producción, pero este es el único que puedo mostrar aquí.
Puede que dentro de poco presente un curso similar de forma online y en castellano.
