Old school material shader (ambient, diffuse, specular) I recently migrated to the new blender and can't find the old way to use material by choosing the ambient, diffuse and specular color (example image of what I'm looking for).
Is there a way to get it back?
I tested to import a wavefront file and export it directly, it change the colors inside the .mtl
Its not the same, but there are similar parameters in the new eevee renderer.
Using the Specular shader you can tweak diffuse + specular color.

Via world properties -&gt; color you can tweak the ambient color

Also accesible in shader editor:
