Hi!
This is done in the
Content Browser.
Just make sure your new dds is correctly located in your mod's folder under the Editor's data folder.
If you want a new resource to use on new items:
- You can add a new texture resource using the add buttons as shown on the linked page.
If you want to replace existing usage of the original texture with your new altered one:
- Right click -> edit the original resource in the Origin (or Shared) mod that points to the original texture file and then you get a modded version of that resource in your own mod. Then in the properties of that resource you can change the source file path to the location of your new texture.
Sincerly,
Kevin
