Two Ways to Import Materials

There are two ways to add a custom material in Playground: apply directly to an object or add to the material library for reuse across projects.


Method 1 — Apply Directly to an Object

Use this method when you want to quickly apply a material to a specific object without saving it to the library.

  1. Select an object on the canvas
  2. Drag and drop your .pmat or .dmat file onto the 3D canvas
  3. A popup will appear asking: "Apply material to the selected object?" — click Yes or No

Apply to selected object popup

  1. A second popup will appear asking: "Apply to all objects using this material?" — click Yes or No

Apply to all objects popup

Selective Material Application

These two popups give you precise control over where the material is applied. By answering Yes to the first and No to the second, you can apply the material only to the selected object — even if other objects in the scene share the same original material. This effectively separates the material, allowing different objects to have different looks.


Method 2 — Add to Material Library

Use this method when you want to save a material for reuse across multiple projects. Once added, the material stays in your library and is available anytime.

  1. Select an object on the canvas — this opens the material library in the left panel
  2. Navigate to the appropriate material category (Metals, Gems, Ceramics, Pearls, or Other)
  3. Click the circle with a plus icon at the very beginning of the material list
  4. Choose the .pmat or .dmat file you want to upload
  5. The material will appear in the library with an automatically generated preview thumbnail

Adding material to the library

To apply the material, simply click on its icon in the library — it will be applied to the currently selected object. To remove a material from the library, click the cross icon at the top-right corner of its thumbnail.

TIP

Materials added to the library are persistent — you can use them in other projects without needing to import them again.

Premium & Advance

Saving custom materials to the library requires a paid plan. Premium allows up to 5 saved materials, and Advance allows up to 100. See pricing details for more information.
