Hey guys, I've had a problem that I've been working on for a few weeks now. I have minimal experience with Blender/Fusion360/ZBrush, however I have been designing a few functional parts that I have printed and work as intended. One part in particular involves two parts (one of which is a small panel) and I want to ensure that the pattern matches between the two as best as possible.

I want to find a way to engrave textures and cracks into the body of the design. I don't have these patterns designed necessarily, but I found some good options on various sites for blender - however I cannot find a tutorial on how to engrave them and then restore them to an STL for printing. I need to be able to specify the depth, and Zbrush seems to only let me apply the texture THROUGH the design.

If someone could help me out with this, it would be HUGELY appreciated. If needed, I can send a similar STL file to show what exactly I am trying to accomplish.

Thank you guys in advanced!!! Love the community and support here.
