Adding edge damage to specific areas of texture

[CorsairtheDragon]

Greetings all! I'm still fairly new to Susbtance Designer and I was wondering if anyone knew how to go about creating and then adding ceramic-type edge damages to the tops of some of the ceramic tiles in a given texture. I've played around with creating specific shapes and then using tile generators to spread them around, but it always looks a little too man-made even with tile generation and offsetting. If someone has a more efficient method of adding such edge damages, please let me know.

Thanks!

Hello,

A common method of applying edge damages is to pass the height map to a Slope blur node set to Min mode.

You can then subtract the damaged version of the height map to the original height map , using a Blend node to extract the damaged areas. With a Histogram scan node, it can make for a useful mask to apply different coloring or roughness values to these areas.

I hope this is helpful!

Best regards.

To add to Luca's answer, if you also use a Tile Random node randomising the tile colour followed by Histogram Scan to create a mask, you can vary the number of tiles with edge damage vs those without.
