32 bit maps
show user profile  herfst1
Hi, I was working in z-brush and it gives the option to create 32-bit maps. I was wondering what the advantage would be? As far as I know 32-bit maps only include the alphas. Photoshop also gives the option to save images as 32-bit and, again, I don't see the advantage. Can someone enlighten me?

by 32 bit do you mean per pixel or per channel?

if per pixel then yea it means alpha, very useful when you want to paint on multiple layers of something and leave it layered(not flattened). Afterwards you can compose the material in max material editor to adjust the influence of these separate layers, gives you easy way to create texture variety.

if per channel then that usually means its an encoding for displacement map of some sort, sometimes thats just a plain 32bit single channel pixel or sometimes its more exotic like vertex displacement.. in the end they all are made to satisfy the need for high detail displacement.

can also do 10:11:11 - gives a little more accuracy than 888.

not sure if any of the regular file formats support that . can generate from floating point formats on the fly for run time medium def quality. sometimes used in real-time engines.

Thank you for your responses.

To be honest I'm not really sure whether I'm meaning per pixel or per channel. I assume with Photoshop it means per channel but as for z-brush, not a clue. It's just that I've seen tutorials for creating 16-bit and 32-bit maps and really couldn't see the advantage for 32-bit as I create the alpha's in Max, but if that means a higher detail per pixel then that's useful to know.

And the 10:11:11, um... I guess I'm going to have to research what and how that's implemented, thanks for the heads up.
