I have never noticed any difference for displacement. Photoshop seems saves only 16 bit HAlf float exrs anyway but 16 bit integer always worked fine for me too
Thank for the quick reply but for working these displacement map in Photoshop should i just work in 16 bits since all tools seem to work with 16 bits and then when finish convert to 32 bits before export?
I am currently struggling to see the difference between my 16 bits and 32 bits displacement, i did a search but nothing was very conclusive and surprisingly i didn't saw any image comparison! Is there a tremendous difference or very slight since most of the Photoshop tools are not working with 32 bits images and many…
No, converting to 32 bit would do nothing for you if done at the end. This would result in larger files but no additional information. Even for displacement, 16 bit is usually enough and 32 bit is rarely needed. You can do some tests in your game engine or renderer to compare the difference between 32 and 16 bit. Working…
If it has been converted to 16 bits, you have removed the additional information, converting it back to 32 bit won't magically recreate it (you could blur it afterwards, of course, but that will only work in certain cases with little to no details).
