That is a Good method for New Units againsttheflow... Gary was wanting a way to alter existing Units in this case. Paint Shop Pro has the ability to adjust any level of Sharpness desired as well as Contrast, Brightness and others.
...Applying more sharpness causes the need to make a New Palette and when sharpening the Unit, the Light pixels become too Bright which causes the extreme look that does not "blend" in a "realistic" way... Sharp
Sparkles is the word that comes to mind
If an existing Unit is Sharpened, it would be best to adjust the color pixels that are Too Bright after applying the new palette.
...Sharpen the Storyboards as desired, Make a New Palette, Apply the New Palette to the Sharpened Storyboards using "Nearest Color Matching" then adjust the Pixels that are too Bright. Save this adjusted Palette as the Final Palette. You can then apply the First Palette to all of the Sharpened Storyboards using "Nearest Color Matching" and then apply the Final Palette with the "Maintaining index" setting.
Personally, I find that adjusting the Contrast and Brightness levels on an Existing Unit to work easier. All Unit Colors remain in their same index so those Unit Colors can be copied to the Original Palette using Pedit Palette Editor in the same Places. The reason to do this is to Correct the Civ Specific Colors, Smoke and Shadow Shades because they will be altered when the Unit is adjusted as well. If this Method is used, you can simply Load the New Palette to the Existing Original Unit Storyboard and Maintain Index.
Best to use a Screenshot of your Game Map as a Background to check your Adjustments when Creating or Adjusting a Unit because we cannot see the results of Adjustments against the .pal or Alpha.pal Backgrounds when working in Graphics Editors.
Just a Note about the Shadow Shades on the Unit Game Palette... I have seen many Units that Alter the Shades on the .pal Palette for Shadows. This Only affects the Preview for the Magenta Shadows. Those Shades will show as their Original Shadow Shades in Game because they maintain index for their original Shades. What this means is a Unit will have the original shadows of what ever shadow slots you use on the Palette regardless of if you change them. Changing the Shadows can make a Preview look better but in game will show the Original Shadows Shades. This is the same for Smoke Shades as well... all indexed.
...We can only Alter the 160 Unit Palette Colors of the 256 colors on Unit Palettes. Because Rendered Images are 16 Million Colors, this means we reduce the Unit Colors 100 thousand times and THAT is just one of the tough factors that affects the Desired Esthetic End Results of Units.
Comparing the Screenshot of the CIV Game Warriors to the Previous and Sharpened Units,
I like the Sharpened Units but without the "Sparkles" and that would require additional Palette Editing to subdue those color pixels.
In the End, Please Yourself Gary
