My exported .mtl seems uncompleted So I created this basic material. I used a random image to do some displacement effect :



When I export my cube and open the .mtl generated, I don't see any image inside my .mtl :

# Blender MTL File: 'None'
# Material Count: 1

newmtl Material
Ns 323.999994
Ka 5.000000 5.000000 5.000000
Kd 0.019458 0.800000 0.006406

Ke 0.000000 0.000000 0.000000
Ni 1.450000
d 1.000000
illum 3


How can I fix this ?
Thank you
While the .mtl format has options for defining displacement, the obj exporter add-on currently doesn't support them.
