Do you have a UV mapping on your object?

Unfortunately no! We often get highres polygon data, and unwrapping these (6-8 million polygons) is a real pain in the arse. And imho not needed for 2-3 procedural noises which come to action in a car.
You need non-UV-3d-noises in plastic, leather and carpaint parts. Things like fabric seats, brake disks, tires and reflectors could easily be unwrapped...

Ok, makes sense.

Thank you Ono!
I really want to understand ISL, but I don't get it where you need posOS, vec3, and when and why.

I agree - would be great with a car paint with a scale that's not dependent of UV-mapping but rather the objects dimensions. Also voroni based flakes - so that they actually have a well defined (and changeable) size and shape instead of just being bright spots - would be even better than what we have today.

Try renaming voronoi() function in the shader to something else.

Works! Thank you!
How can I access the color? It's not that simple, I suppose...?

The blue-pink of that material...

Will these options ever be integrated in a more user-friendly appeal?
It's good to know they exist, but adding them inside the plugins would be a huge step ahead!

Yeah, I'll definitely fight for making these kind of ISL mats UI based. See the posts here:

"Oh this is sooo nice... I definately want this material as a complete Indigo- / cindigo material for easy editing and use; encapsuled in a way. Base color, flake color, flake intensity, flake size, coating parameters, bump parameters.
And finished.
Awesome work, Oscar!"

Oh yeah. I think it's not that easy. But implementing all noise functions and types in 3D in all channels would be a giant leap.
Full interface access in the plugins would be another. With optional sliders, input fields and color fields.
