I'm trying to get good with the new Physical material system and I'm liking it. One question I have is how would I go about adding a car paint flake effect using this system? Ironically, the material library's car paint examples are using legacy materials and layers. Can the flakes be done withing one Physical material?
-
Hi there,
The first example is the car paint from the material library manually converted to physical. And the second and third examples are from scratch just using the physical mat. I hope that helps.

Yes, that's very helpful. Thanks for your help.
-
You're most welcome! :)
-
I believe there are issues with the C4D asset browser in R25 with layered materials. These Corona materials don't import.
-
How come?
All components import fine here (R25 + v8 daily from Dec 16 2021)
Note:
Corona Materials are imported via Corona's Material Library. Unless you made your own assets/presets from those. But those also work.

Do I see tiling on 3. image ;)

Indeed you do! ;) Next time, I'll use something seamless. :D
-
Have you tried Maxon Cell Voronoi? Potentially without triplanar needed?
-
I don't see why that wouldn't work ;)
-
I'm just trying to tweak the noise scale and contrast to get something working but I'm certainly no expert!
-
Here is what it looks like using Cell Voronoi. Hope that helps.

I really don't get how you create reflective Flake Car Paint with the new Physical Material... to me also the shown stuff does not look at all like Flakes?!
-
i would try adding a normal map for flakes, similar to this:
https://docs.chaos.com/display/OSLShaders/Flakes+normal+map
bump isnt enough in my experience to make ok glittering flakes:
there are many if you do a google search or you can pretty easy make them yourselves
-
Physical is just fine & has everything it needs...
v.8 is toxic :)

Wow!
Do you mind sharing a Picture of your Material Structure?
-
I would assume his material setup might be similar to this...

-
Basically, yes ;)
-
I am surprised how difficult it is to match your results. Seems pretty straight forward, but can't get it to look like that.
-
oh, I wouldn't bother matching the result,
specifically, it's a unique procedural mix based off of what's shown
just do it to your taste
