To use this product, look in the DAZ Studio half of your content tab. Scroll down to the folder labeled 'Bryce Shaders.' In it you will find one or more folders labeled by category as seen in Bryce's material library. Open the folder to find the DAZ Studio presets for the various textures.
To apply the texture, select the figure or object in the scene (or scene tab) and also in the Surfaces Tab. To open a tab you don't see, go to VIEW –> Tabs –> Surfaces (or whatever the tab is that you want).
Once you have the figure or object selected in the scene and the surface or surfaces for it selected in the Surfaces Tab, then double-click the shader preset that you want to apply.
Please note that since these are Bryce materials, they will *not* appear in the preview, just as in Bryce. You will only see them when you do the render for your scene.
