Description
Blend is a 3D format developed by the Blender 3D modelling application to describe 3D scenes. The file may also contain sound, scenes, and effects used in animation.
3D file formats are increasing by the day and this isn't a bad thing. The only quibble comes when 3D format file users have to collaborate on a file. It's impossible to work on one file when using different file formats. And that's where 3D file conversions come in.
