Loading an **obj file** (with **loadModel()**) and then specifying the texture (with **texture()**) is not possible if there is no texture (in case the colors are specified in the mtl file) or if there are several images for textures in P5js or Processing.

**So how do we do it?**

I just realized that you can use the **Blockbench** (_ **it’s FOSS** _) program to import (or make yourself a new shape) an obj file and use it to easily redo the texture.

**It exports as an obj with only one texture!**

[It works : test here](https://editor.p5js.org/EricRogerGarcia/sketches/29N3u756s)

Yes, it’s just a first try with Blockbench (and just a cube) but it’s an export to an OBJ file with the texture done with the program.

Besides, it doesn’t seem too complicated to use!
