Hi everyone.

If you work with low poly models (for example, those created by Synty Studios) you probably noticed that most of the models use a single material and a texture atlas with a series of color palettes arranged in a grid like pattern. If you want to change the colors of a model, first you have to import the model in a 3D application (3DS Max, Maya or Blender) and find which texture colors are used by that model, then you have to import the texture atlas in an image editing software like Photoshop or GIMP. The next step can take a considerable amount of time as you will most likely have to change the colors and export the texture multiple times before you get the result you want.

To reduce the time needed to change the colors of a texture atlas, I created an editor extension called Palette Modifier, that allows you to do that directly inside Unity.

Main features:

  • Per object colors

  • Break color sharing.

  • Texture pattern tint.

  • Color gradient.

  • Save color changes as a new texture atlas.

  • UV Inspector.

Other features:

  • Color groups.
  • Color highlight.
  • Reorderable list of colors.
  • Foldable list of colors.
  • Non destructive workflow.
  • Reset single color to its original value
  • Reset palette colors to their original values.

Per object colors
Palette Modifier finds and displays in the inspector only the colors that are used by the selected game object.

Break color sharing.
PM creates a copy of an objects mesh and moves the UVs to a section of the texture that is unused by other objects. This feature is useful when you want your object to have unique colors that are not shared with other objects.

Texture pattern tint.
Palette Modifier allows you to apply a color tint to segments of the texture atlas that have texture patterns on them.

Color gradient.
You can apply a color gradient to all the object colors or to just a few.

Color groups.
If your model has many colors you can arrange them in groups and give the color groups distinctive names.

Color highlight
The color selected in the inspector can be highlighted. This makes it easy for you to know where this particular color is used on the object.

Reorderable list of colors.
The object colors are displayed in the inspector as a reorderable list.

Foldable list of colors.
The colors list can be collapsed to make the list more compact in the inspector.

Non destructive workflow.
The changes you make to the texture atlas are not automatically saved to HDD. This means that you can experiment with different colors without being worried about destroying your original texture atlas.

Save color changes as a new texture atlas.
If you changed some colors, but don’t want to lose your original texture, you can save the color changes as a new texture atlas.

Progress Update.

Hi.

In the past week I made some changes to Palette Modifier code as well as added new features.

In the video bellow you can see how the Texture Grid asset is created. PM uses the Texture Grid asset to find the texture colors that a model uses.

Previously you could only change the flat colors of a model, but now you can also apply a color tint to parts of the texture atlas that have texture patterns. Color tint works the same way as the material color, but instead of it being applied to the entire texture, it is applied only on the parts of the texture used by the current object.

Another thing that changed it how you break color sharing between models. Previously if you had several models that shared the same texture colors and wanted to have a model with unique colors, you had to open a Palette Modifier window. In that window you had to provide a reference to the object with the PM script, a reference to the Texture Grid and the color of the unused space on the texture. Now you only need to press a single button.

The video bellow showcases the color tint and how you break the color sharing between models feature .

Hi just checking in on this. When will this be available on the asset store?

Hi. Yes, it will. I’m currently doing a beta testing of PM with a small group of people, to make sure there are no major bugs.

Progress Update 2

Hi. It’s been a while since the last update. I’v added a couple new features as well as improved the user experience.

  • When you add the Palette Modifier script to a GameObject, you no longer need to assign a Texture Grid asset. You still have to create it, but the task of assigning it is now done automatically by PM.

  • If you select a texture atlas, right click it and create a Texture Grid asset, the selected texture atlas will be assigned to the Texture Grid asset. The Texture Grid asset will have the same name as the texture atlas plus the TG_ prefix.

  • The PM settings in the objects inspector are now displayed in tabs.

  • When you create a Texture Grid asset, you don’t want to have overlapping Flat Color Grids or Texture Rects, but there was no way to know if you had any overlapping grids on the canvas. Now if the Texture Grid Editor detects that there are overlapping grids, they will be colored in red.

  • I added the ability to copy and paste a Flat Color Grid or Texture Rect.

  • I added the ability to reset a color field to its original value.

  • I added the ability to reset the colors of a palette to their original values.

If this works as intended you’ve created something great man. Any timeline for when it will come to the store?

Palette Modifier v1.1.0 is now live on the Asset Store.

This update adds a new feature to PM. The UV Inspector. You can use it to find which texture colors are used by a particular model and build the Texture Grid gradually.

I think you should readjust the name of the asset to have “color” in it. That way you would get more pings on the store search. Or at least add a tag. Because this thing is pretty cool.
