Pixel point value is weird in displacement map

ZBrush Usage Questions
#1

Hi everyone, I am a newbie of using zbrush. I have a problem of exporting displacement map.


This is my sculpting scene in Zbrush. You can see there have a very popping mesh on the plane.

This is my setting before I exported the map.


I dragged the map into Nuke to see the value, it is weird that all of those values are under decimal…


I exported obj to Maya and see what happen, the result seems alright…

Can everyone explain what happen of this phenomenon? Have I set something wrong when I exported the displacement from Zbrush???

Thank you!!!

I’m not sure what the problem is. The image of the displacement map in Nuke will be adjusted so that you can see it - otherwise it would look just grey. The actual values are small because with a 32bit map the range is vast.

Thank you for your reply. I think the phenomenon is weird because I am just following steps with this article:

His exported displacement map pixel value is align to the render result:

But mine is really weird:

It is appearing nothing because the pixel value is too small. ^^^^
