Dirt texture using nodes

[joan]

Hi all!

I'm going crazy trying to add AO to a material, what I am doing wrong?



Thanks in advance!

In your case you have 2 brdfs with weight=1.0 means only one will be seen, so in this case you need to use Dirt as Weight:


But I could also suggest doing smth like mixing dirt with diffuse texture (i'm showing 2 setups here: using mix and using layered):


Also check "Invert normal" option and a trick of how to adjust radius if radius is textured:

As usual, fantastic explanation, Andrey, thank you!
