It can simplify the parameters of the material and reduce the learning threshold of the material system. Material templates are customised by default and contain the most commonly used basic parameters. The drop-down list can be changed to other materials such as Transparent, Water, Car Paint, Replacement, Cloth, Custom Alpha and Multimedia, etc. You can quickly assign materials to their corresponding categories to simplify the material editing process. Different material templates have different adjustable parameters. ## Library preset material Preset materials are the large number of materials available to the user in the library. After selecting the desired material in the material library and downloading it, you can directly apply the selected material to your scene. The downloaded preset material already contains material maps and adjusted material parameters, so you can apply it in your scene directly. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.d5render.com/user-guide/material/what-is-the-difference-between-a-material-template-and-a-library-preset-material.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
