When I try and create my displacement map for my model, it goes through the process of creating it, then nothing happens, it does’t go to the texture channel so I can export it… what do I do?
Zbrush will shoot it over to your alpha pallete, go look there…then you have to select it.
Thanks, I found it now, however when I ever create a displacement map it just turns out blank grey!

Okay, you’re going to have to supply a little more information that what you are. Is it going into another program, what one, how did you create the displacement map, are you using the displament map exporter, etc.
Ok here goes, low poly model made in max, and unwrapped in max, exported as .obj to Zbrush, sculpted detail, went to subdiv level 2, set dispmap size to 2048, DPsubpixels to 2 , Smooth UV OFF then hit create. After creation displacement map is in custom alphas like you said, however almost completely blank. Displacement Exporter won’t work for me, every time I hit create all it says there’s an error.
This is driving me crazy! Normal maps look awful compared to actual geometry 
Your going to have to do some research in regards to the displacement exporter settings and max.
Normally when you create a displacement map you are going to go down to the lowest subdivision level, if you stored a morph target then you are going to switch that too.
For Max, I haven’t tackeled that beast yet so this is as far as I can go.
Good luck
I don’t think the problem is with max, when I create the displacement in zbrush is when the problem occurs. The map as you can see looks almost blank, even though I have 8 subdiv levels! Weird. Thanks for your help anyway.
I’ve got the exact same problem. the problem is not to render it out in another software, it’s when i try to create the displacement map in zbr.
The alpha just comes out plain gray. any suggestions?
Don’t know what to tell you folks other than it works for me.
Are you sure that they are UV coordinates applied to the obj? I don’t mean that to sound below you but one is never sure about the other posters level.
So is your detail minor or very exagerrated? If it’s minor then the map might look totally grey…but it’s really not. Can you post a pic of your model in ZB at the highest sub-d?
um… now i feel a bit stupid, i did the uv’s but never saved the file, when i opened zbr the next time i assumed all was ready to go :lol: .
My bad.
Thanks anyway
Don’t feel stupid it’s all part of the process, okay?
Learn and move on.
Well when in max, I unwrapped the model, saved the uvs and exported the obj with texture coordinates so it must be right? Also, I can render normal maps fine - it’s just the displacement maps that come out messed up. And also, there is lots of small detail but also lots of larger detail, it would definitely be visible. I know this because I applied the map to my models and just looks bloated with none of the detail I added.
when you do a uv check in zbrush do you see the uvs youve created in max?
just to make sure… you need to go down on your subd levels in order to get a good displacement map.
Yep, i’m at subD level 1, done uv check all is fine.
hmm,
i had the same problem. and solved it… thing is i dont know what i did anymore.
maybe i just restarted the program and tried an other mesh… did you try that, just to see if it is not that particular mesh that is giving you the problems.
ill keep thinking for you…
Definitely not the mesh, tried it on another one and the same thing happens.
Well, one other thought might be that you are driving the displacement map in Max too much. When you create the displacement map in Zbrush and go to the alpha tool roll out panel, at the bottom you should see an Alpha Depth Factor number…that number should be the number you input to drive your displacement in whatever proggie you’re in.
Ahh I dunno what to do man, this it totally crippling my workflow, here’s a displacement I just rendered (dsubpix = 2, map size = 512, smoothuv = on)… this doesn’t look right to me, not to mention the edges are totally screwed up.

try deformation/unify and recalculate the displacement map
Nope, didn’t work…
