Dear all, I’ve been looking to create a model with some decent cracks and damage decals.
-for a while, I’ve held a bunch of (97) zBrush brushes (ZBP) but have wanted to be able to use them in Nomad.
I managed to convert 88 of them and turn them into nomad brushes.
Timeline / origin:
They originally came from a website in 2015 (zBrush user - Simon Fuchs), who created them from some designs a man called Paul Tosca created. Simon credited Paul on his website (where I got these), and I’m crediting Simon here. -they were offered up for free, so I am confident no harm done here. 
The process:
- cycled through each ZBP in zBrush, exporting a TIF each time (to maintain 16-bit depth)=
- brought into Photoshop to re-export as PNG (preserving the bit depth of 16)
Brought into Nomad and took the default Clay brush, cloned, assigned the Alpha, inverted pixels (if needed), adjusted the falloff occasionally (if needed).
Finally, saved each brush of course, and uploaded them here.
To use:
Download Cracks & damage (alphas).zip
- Open Files app (iOS), extract the zip. Place the extracted folder in Nomad > Alphas
do the same again with Cracks & Damage (brushes).zip
but place folder in Nomad > Tools
Brushes should now appear when Nomad is restarted 
Disclaimer:
- the thumbnails for the brushes are not ideal (they are simply taken from a snippit of the alpha image itself), but the brush names themselves should hopefully make it clear.
- This is the first time I’ve ever attempted authoring a brush.
Enjoy, hope you’re able to create something great
