The textures in the Dirty Pictures Library, included with Dirty Pictures, all have texture-specific settings already saved, but if you add your own textures to the library, we’ll need to know how you want them to be applied. You can set a default blending mode and opacity for textures that don’t have saved settings via the sliders in the Options window. Once you save the settings for a texture, these settings will be overridden for that particular texture. Anytime you change these settings, you’ll be prompted to generate new previews for textures that are affected.
The default setting is Hard Light and 50% Opacity. If you have a favorite starting point for applying textures, you can use your own settings instead.
