How to create Raw File for unity white Photoshop

Hi, I want Create a Raw File in Photoshop for Import Hightmap Terrain, when Save a Hightmap 16Bit with Raw Format and set header to 0 then Export to unity not worked but Output is not my Asked !!!!!!!
What I do ??????

 

This is how i do it: create terrain, export heightmap, open in photoshop, make changes, save, back in unity; import (with default settings)

 

I have read your post and you can find how to create it by visiting this page. I can describe you how to create it but this will help you much. http://www.jasonsturges.com/2012/12/creating-a-terrain-for-unity-3d-with-photoshop/

 

This is a super old thread, but,

in Photoshop 22.5 (That's the one I'm on. It's probably the same in recent versions)

hit CTRL + S as if to save the file
"save as" popup will appear, with ONLY PNG, JPEG, etc. options (this is not helpful to us)

Ignore this, and in the bottom right of the save window is the "Save a Copy" option. A new window will pop up, and you'll be able to change the filetype to Photoshop RAW (.raw)

Works for me just fine and I can import into Unity's terrain, and make any adjustments changes I want.

I did this to break up a previously massive terrain into multiple little ones.
Hope this helps someone.
