Use 50% grey as zero height?

Hi there!

 

I'm looking to export height maps that use 50% grey as my baseline zero height because i'm displacing negatively and positively. However, when viewing my height channel in Painter, 0 height is always black and setting height to a negative scale doesn't seem to write any data into the height map. 

 

Could someone offer some insight on how I might set this up? For further context, I'll be rendering in Blender where the displacement has a setting to define the midlevel which I will have set at 0.5

Don't be misled by the standard black height display for negative values. Those negative values are there - they are just not displayed as standard.  You can go to Display Settings > Channel Display and check 'Use +/- color for HDR values' which will show +ve values in green and negative in red (0 will remain black).

 

Whether you do the above or not, when exported the height map will become a greyscale and for example if exported as 16 bit PNG will be centered on 0.5 which you can plug directly

Thanks, Dave!

 

I had been misled by the standard black height display and have enabled the settings you've suggested and it is much better! Thank you!
