Random color for Car model in Container

[osukas]

Hello,

Im making an scene where I have 500+ cars on it.

Each model of car is beeing loaded with a "Container" to keep the main project light, I want to add random color to the CAR_Paint. Because im loading the Vehicle with a Container, I can´t use the random Material ID modifier

There is a way how to get random color for the material?

EDIT: Well, using the containers might not be a good idea, Im reopening my project and has like 20 min trying to open and the RAM is at 98%

If im using Containers, this works:

each element with carpaint is different. But because the scene is too heavy Im changing to .ASS

but this shader doesnt work, all the cars are the same color

Have you tried doing this with Arnold Operators?

I tried with the Operators but still didnt get the Random Colors, because i had to fix this quick I had to brute force my way out and manually set different colors.
