Title: Red Leather Material test
Post by: cobra1979 on 2014-07-14, 20:53:09

Hello, does this looks good to you? I'm quite not sure. I was going for a leather material but I'm afraid I've failed. Can't point exactly why.

Well, here's a little tip.. Find a reference to the leather material you want to achieve, observe it, and then go and try to replicate it. It doesn't look right to me because of many things... But I don't know what you're aiming for.

observe, and be the judge yourself... Is this, what you want to achieve?

Thanks for the tip, the Leather I'm aiming for isn t exactly the same but I've tried to replicate the one you provided for practice.
I think the reflection was to dim and the color wasn t quite right.
Here is a lowrez update.

Tiling seem to be too big. at least 2-2,5 times bigger it is in real life.

I've fixed the size of the tiling.

What references are you using for this material?

I've used the one provided by lacilaci at the beginning of the tread and then switched to black because I get bored tryin to get the red one right. I'll go back to it later. Why?

With the references it is easier to say if you are close or not. The red sofa it is close, but I think you need to work a little more how reflection is working. What IOR are you using? If you notice in the reference the sofa is highly reflective in particular close to 0 degrees.

I see, I think you re right.
I've used the default ior but I'll try to tweak it or use a reflection pass.
thanks.

I think the leather looks pretty good in the end.. definitely better than the one at the beginning :)
