Hey guys so I have a 16bit Image I want to edit to put on the terrain.png file. Whenever I place the image it has the 16 bit look until I confirm the place, then photoshop smooths out the image and adds a bunch of pixels.
How can I solve this?
What you want to do is resample the 16px tile or tiles to your new terrain file's resolution ( 32px , 64px or 128px ) before placing them. I assume you're transforming them and that is what is creating the interpolation you're seeing. Try it this way...
Open the source image
select the tile you want
make a new file ( it should default to the size of the copy you just made )
change image size to the new dimensions ( ie 64 ) USING NEAREST NEIGHBOR INTERPOLATION! ( it also reads "preserve hard edges" )
open target image
That should get you a cleanly resized tile with no interpolation. If I'm misreading your situation just clarify and I'll see if I can help you out.
