Any plans on replicating the radial micro-scratch effect?

[bigapple90]

Hello,

Are there any plans on ways for V-Ray to create the radial micro scratch patterns as seen on cars? For example: here
This effect is not only seen on cars but on other surfaces such as plastic. As of now I can only see the use of finely detailed bump maps at varying sizes to create this effect, which is time consuming. Or perhaps some post-production work...but since the radial scratches "follow" the highlights this may not be suitable for animations. I was hoping Chaosgroup was working on a simpler, faster and better looking solution to help push the realism of V-Ray even further.

Thank you.

id imagine a suitable scratch map could be used on any number of projects.. you only need to create it once. if the scratches are right, and small enough you will get this effect.

There was some discussion about similar effects here:

yeh ive been waiting for a conclusion to that thread...!

haha as have I. The methods proposed by kweechy are similar to what I was working on as well. However I just wanted to know if Chaosgroup had any intention of adding the radial scratch functionality that could be easier and better than bump stacking.

It is not impossible, certainly... I'd imagine most car visualizations don't really go for scratched paint though It might be a while before we get to that though.

hehe I guess. But it's a nice option to have . And yea it's not impossible, with a more work I think we can achieve pretty good results.

Created this in a few minutes with some noise maps. May be better to use bitmaps...

Id love to see this material!

Thanks

I'd love to see a slow camera move towards it to see how it reacts in terms of pixel crawling and aa sizzling - looks great as a still though!

I actually lost the file containing this material. But from what I remember it was a vray blend of materials with noise maps in the bump slots. The noise map was stretched with tiling to fake long thin scratches. Each vray blend layer rotated the direction of the noise map by 45 degrees. I think i may have used 3 layers total and the base layer as well.
