MAYA and ZBRUSH DISPLACEMENT MAP ISSUE

[system]

Ok, so this may seem long winded but I’ll try to make this understandable. I bullet pointed my current workflow so you can see where I went with this project

Workflow

Created a sculpt in Zbrush (using a base sculpt a friend had given me to start on) so it wasn’t dynamesh or anything

I then took that sculpt into Topogun and retopologized it.

I exported the new retopolgized mesh into Maya and did the Uv’s

I brought the new low poly mesh back into zbrush

I then used the “project all” method to project the high poly details onto the low poly mesh that i had subdivided a bit so it could handle the detail.

So now I’m stuck. I need to create a displacement map so that I can take those high poly details and use them on the low poly mesh in maya. However, everytime I create a displacement map it ends up almost completely black and useless. I feel like I’m missing a step or something here. From my understanding the new mesh should still have the low poly uvs etc so I don’t know whats going on. I’m using ZBrush 4R6 and maya 2015.

Can someone give me an idea of what i’m missing. I’ve included images of the workflow so you have an idea of what im looking at.

Can you post a picture of your displacement map?

Are you creating your displacement map on sub d level 1 of your new re-topolgized mesh in zbrush?

What displacement map settings are you using?

I’m getting the same problem with 32bit displacement and vector displacement maps. Do 16 bit work for you?

I find that the settings have to altered according to each individual sculpt, so try increasing the DPSubPix to 2 or 4 and disable Smooth UV. You can also try adjusting the Approx Editor settings in Maya for more detail

I have the same problem, I created the map in 32 Bits. but i can see some information in NUKE. I increase exposure in photoshop or gamma in nuke and I get to see something but don’t work in maya with vray. Help please.
