Working with Materials in Twinmotion

Materials

Assigning Materials

In Twinmotion, you can manage and assign materials easily to enhance the realism of your scene.

1. Navigate to the Materials tab at the bottom of the screen. You'll see the materials imported from your Rhino file.
2. Open the Library on the left panel.
3. Go to Materials and select one you want to use.

To replace materials, simply drag and drop the selected material onto the object in the viewport. By default, this applies the material to all objects sharing the same original material.

You can refine how materials are applied:

• Click the icon with two intersecting circles at the top center of the screen.
• From the dropdown, choose whether to apply the material:
  • To all instances of the same material (default)
  • To a single object
  • To a custom selection of objects

Material Settings

Access material properties by using the eyedropper tool (pipette icon) at the top center and clicking the material in the viewport. The Material Settings panel will appear at the bottom right.

Explore the following key settings:

• Tint: Adjusts the material's color.
• Grunge: Adds dirt/wear patterns for a more realistic, less repetitive look.
• Normal: Adds surface depth using normal maps.
• Parallax: Adds realistic 3D depth to 2D materials (enable if available).
  • Tip: Sometimes you'll need to copy the normal map into the parallax input slot.
• Emissive: Makes materials emit light.
• Two-Sided: Forces surfaces to render on both sides.
  • This is useful for thin surfaces that only display from one direction by default.

UV Mapping in Twinmotion

To ensure materials scale and align correctly across objects:

1. In the Properties tab, go to the UV section.
2. Under Triplanar, set it to World Space to align textures uniformly across objects.
3. Enable Randomize UV to break up visual repetition—great for surfaces like grass or gravel.

While Rhino has more UV mapping tools, for most use cases, the settings in Twinmotion are sufficient.
