Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

BUM to OBJ Conversion

What are BUM files?

The BUM file extension is associated with Poser — a graphics program specialized in modeling 3D human figures and used for creating animations and digital images. A BUM file can contain static or dynamic bump images.

What are OBJ files?

OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
