Using Surface->Noise effectively?

[mad187]

Guys, How do you go about using the Tool->Surface->Noise effectively on a 3d model. Say its a simple brick I wish to add noise to. How do I then transfer this to normal maps or displacement maps?

The reason I am having issues doing so is that when applying the Noise. It looks good but upon hitting the “apply to mesh” button, the resolution of the model causes me to loose most of that detail and softens up the noise which gives me a very different result.

I’ve tried using HD Geometry and then applying the noise but I don’t think that is how it really works. Is there a way around this? I’ve been recommended to use the noise brush…but is there a way using this method?

Need about 1mil poly’s for something like a brick to retain most of the information. I’ve using it a lot on statues recently and those are around 4mil plus before I add noise. So if you’re still fairly low poly you just need to divide a couple times.
