Japanese anime studio Khara is switching to Blender, a free and open-source 3D creation software, for their primary 3D CG tool. The reason for this switch is mainly due to the high costs of their current tool, Autodesk's 3ds Max, which can be a barrier for smaller studios and freelancers they collaborate with. Khara is currently working on the film 'EVANGELION:3.0+1.0' and will use Blender for some parts of the production. The studio's decision to switch to Blender is also driven by the software's improving functionality and the potential for faster development and customization through its open-source nature.
