importing model into blender

[wirstrom]

Hi,
Thank you for a great contribution!
I am trying to import the created mesh.obj into blender, together with diffuse_albedo.png, specular_albedo.png, and roughness.png. I do this by creating a Principled BSDF material in blender and assigning the images to Base Color, Specular, and Roughness slots, respectively. The results are not what I expected. The images look dim, which I assume means that roughness is too high? On the other hand, the test-images rendered by python render_surface.py ... --render_all look good.
Any help is appreciated!

Did you set up the lighting properly?
