ZBrush Usage Questions
#1

Hey guys, long time stalker here. I’m working on a model and some accessories. Making some arrowheads at the moment, but I cant for the life of me figure out how to get a chiseled obsidian type of cut into my object. Here are some examples of what I"m trying to make.

I’ve tried using higher res images to make alphas and while it certainly drops a “texture” on it, the feel and depth that a chisel would have on the rock is completely non existent.

Note: the images are straight off google, I do not claim ownership over any of these reference images.

Clay tubes with low focal shift of about -90, trim dynamic of HPolish, maybe some Dam_Standard to accentuate edges. Be kind of rough with it. I’m gonna have a go at it, see if I can pull it off.

Thats not a bad idea, I was having some level of success using Trim Front, but its still not quite there yet. Its gonna need a combination of smooth and hard edged areas

You can also use pinch with hPolish to accentuate the sharp edges, also polish crisp edges.

So I’m hoping this is something in the right direction. I used the chrome2 material at about 90% grey. I made sort of sweeping half circles using clay tubes at -80 focal shift repeating like this ))), then came in from the other direction ((( and used Dam_Standard to sharpen the edges. Then also some trim_dynamic on the cutting edges.

Woa dude! Thats fantastic! Seriously that looks really great! I had to stop to eat some breakfast since I’ve been up since 4 am lol. But I’m gonna give that a shot. Thanks!

Glad to help! If you could post an update when you’re done, I’d love to know how it turns out.

Heres my version. Your advice helped a ton. I think I was staring at the computer for so long I just wasn’t thinking about the process but was just wasting time noodling on the thing. The process was similar to yours, I used to the clay tubes brush as adiviced, pulling out the sharp edges with dam standard brush. I used clay build up to get the form back in certain areas that I pushed too deep, pulled it way out so I had material to carve out from. Then back in with Clay tubes. After I was happy, I applied an alpha to it and the mat cap.

Random question How do I change my avatar? I dont want an arrowhead as an avatar lol.

Awesome, happy to see it worked out.

As for the avatar, I’m not sure, all I know is it’s the last uploaded image, not sure if you can choose a custom one.

You could also try some of the mallet brushes along with some alphas.
