I'm completely new to Blender and I have to do an apparently simple thing. Open a blender file and export it as .obj with its .mtl file. When I look at the model with Material "view" everything is ok (colored as I want) enter image description here when I look with Solid "view" everything is grey enter image description here Now I go to export .obj and I select "Write Materials" creating the .mtl file. Unfortunately, all the created materials are:

newmtl Material.007
Ns 96.078431
Ka 1.000000 1.000000 1.000000
Kd 0.640000 0.640000 0.640000
Ks 0.500000 0.500000 0.500000
Ke 0.000000 0.000000 0.000000
Ni 1.000000
d 1.000000
illum 2

that is something like grey. How can I export the true materials?

  • $\begingroup$ ok, as far as I understood I have to redefine the materials in my .mtl file since blender is not able to export them. Is this the answer? $\endgroup$ – Alex Gimondi Sep 24 '18 at 14:18
  • $\begingroup$ What is the purpose of this OBJ file? Do you really need material information? $\endgroup$ – Duarte Farrajota Ramos Sep 24 '18 at 14:28

    $\begingroup$ I have to import the 3D model of the car in another program to make some videos. Without the material file the car looks grey. Actually, I have seen that modifying manually the .mtl file makes the final car acceptable, could not be the best solution but is enough for the moment. $\endgroup$ – Alex Gimondi Sep 24 '18 at 14:35
