Textures: Importing, editing, exporting

How to edit images and preserve transparency

Rache Bartmoss once said: the first step to importing a texture is exporting a texture.

For documentation on the Wolvenkit Import/Export tool, see here.

Exporting a texture

1. Add the texture you want to overwrite to your Wolvenkit project.

   1. If necessary, move and rename it. You should stick to the game's naming convention.

2. Find the Export Tool (Tools -> Export Tool) and export the texture.

3. You can now find a png file in your project's raw folder.

Editing a texture

Editing textures is straightforward: just change them in your image editor of choice. The only hitch for reimport is the transparency.

Wolvenkit supports the .dds file format, but since that is more complex, we won't talk about it here and stick to the .png format. If you're using .dds files, you probably know what you're doing anyway :)

Paint.NET

Paint.NET is a free image editing software for Windows. It supports PNG transparency out-of-the-box.

Use 32-Bit to get the highest available image quality.

Adobe Photoshop

To export with transparency in Photoshop, you need an alpha channel. Fortunately, creating one is simple. (For the initiated: The alpha channel is just a layer mask over the entire image.)

Find the Channels palette at the bottom right of your Workspace and add a new channel:

You now have an alpha channel.

Your image will turn black now, because the selected alpha channel will not have transparency yet.

To get your image back, select "RGB" on the Channels palette — but we'll stay on the Alpha channel for now.

In the layers palette, use your image as selection by ctrl+clicking on the layer's icon:

Layer to selection

With the alpha channel selected, fill your selection with white to mark the transparent parts.

The fastest way to do that is to press d, x, delete

You can now save your image as a PNG with transparency. If you have exported a texture in the first section, you should overwrite that file.

Importing a texture

• Find the Import Tool (Tools -> Import Tool) and select your texture.

• If you have stuck to the game's naming convention, Wolvenkit will select the right preset for you. Otherwise, you need to select the right preset:

  • TexG_Generic_Color for a diffuse/albedo

  • TexG_Generic_Normal for a normal map

  • TexG_Generic_UI for anything that you want to use in .inkatlas files

  • … etc

• If your texture is upside-down, uncheck the box for VFlip.

• Click the "import" button. Your .png will now be imported Into the .xbm file.
