@williamatics Could you use a texture as a displacement map ? For example taking a dashboard image, turn it into greyscale values and use the microdisplacement tool? Might be overdrivensolution though, perhaps a simple image would do the trick.
To be honest the “traditionnal” kitbashing technique is not that much time consuming once you do it a couple of time you can even instantiate groups of assets rather than individual assets. Just make sure it doesn’t look too repetitive then.
