Seems like we missed one Portuguese Blender book, but luckily someone was kind enough to point it out.
The book is called "Modelagem e AnimaÃ§Ã£o com Blender" from Ã‰RICA by William Pereira Alves and it was released in mid 2006. The book focuses on understanding the interface and modeling, while covering the basics on animation.
Yet another resource for all of you Portuguese readers out there.
Have a fun reading.
