Porous foam?

How do I create a porous foam material with Flamingo?

In particular, I am interested in visualizing Foam rubber, also in closeup view, with individual pores visible.

you will need a good tile able photo of the pores. You will then make two copies and make one of the copies black and white.

the color photo goes in the color channel of the material, and the black and white goes in the bump channel.

that should get you started

Thanks for the suggestion, @theoutside. It’s better than nothing, although edges will look unrealistic. A procedural method is much preferred. I more and more get the impression that the primary use of Flamingo is architecture. For product rendering it seems limited.

If someone could provide a link to a tileable pores texture that would be great!
