Getting random colors on Procedural (.ass file)

[osukas]

I'm adding a lot of car models in my scene, because they are heavy I'm exporting them in .ass ,and allows me handle all the data in scene.

I made a shader that gives me a random color if I duplicate the geometry. But when loading the .ass file. All the copies use the same color. This is the shader I'm using

 there is a way to get the color randomized? BTW the cars are parked, so if there is a way to get color based on world position that can work for me

As far as I know, the color needs to be reassigned via operators in the case of .ass files. But I don't know much about this issue. Look for "Arnold operators"in the description

Followed the tutorial, and doesnt work, all the procedural objects are the same color, doesnt pick the "Node Hash"

If i add normal spheres to the scene and assign the material, i get the random colors

But i dont get it from using the operator in the "Procedural Object"
