Export

The 3D model should be exported as such:

  • geometry export format .OBJ

  • material export format .MTL

  • exported file size < 1MB (on average)

  • set the Y-axis as the upwards axis in the export settings

Geometry and materialCopied!

In case an item consists of multiple parts, all its parts must be exported into a single .OBJ file.

It is important to export, together with vertices and faces (v and f), the vertices normals vn and texture coordinates vt.

The materials used in the example (e.g. usemtl fabric ) are defined in the .MTL file associated with the object. There should be a single .mtl file per item. Inside the file different material definitions can exist.

The correct assignment of all the values to the appropriate parameters will be taken care of by the software performing the export. In case a texture is to be applied to the item, it is important only to note (and make sure) that the parameters concerning textures are present inside the file.

For example, in the example there have been defined:

a diffuse texture for the fabric material

a diffuse texture for the fabric material

map_Kd -s 2.999999 3.999998 0.000000 BlakeGreyWashTeak_dif_Map.png
