Hello everyone, i've got a probelm:

i'm trying to get a good car tire material but until now i'm not very familiar to the material editor. all my mats dont look like the material is supposed to look like.
i hope someone can help me getting a good material.
i can upload some tests of me,but i'm doing this this night, i've to go now

the mat should look like this









best regards

You're only interested in the rubber material itself ? i assume it's not the threading on the tire. If so then tire rubber like that shouldn't be too tricky to do

threading will require displacement maps with is out of reach for maxwell

[rivoli]

not really, tyres like that are usually modelled.

[Matthias Rudolph]

the thread is modeled, i just need a good rubber mat.

this is what i've got so far:


and here and old and not uptodate render of the tire

[Pierre Caron]

I suggest you increase roughness and you've got it

[Maximus3D]

Great tire and rim model wow!

Personally i'd slap on a roughness map in separate layer with a low blendvalue like 5-10 or lower or something like that so you have some slight unevenness in the specular highlights of the tire. It breaks it up a just a little to make it more realistic looking.

ok, i'll try it

[Matthias Rudolph]

ok, i worked on the tiremat again and now i'm quite satisfied:D



now i'm gonna render the complete wheel and i'm trying to use the sidewall bumpmap

[Pierre Caron]

Well done
Now I would use a bitmap to add some variations in roughness as you can see on your ref photo.

[Maximus3D]

That looks pretty close Matthias good work. Unless you already done what Pierre suggested you should try that, it helps. And then re-render it again with more light on the threaded area aswell so we can see the surface and also the sides how it interacts with light.

update:

[Pierre Caron]

Try to put something like that for roughness :
