Objects with no UVs applied are displayed in a flat purplish color.- **Clay**: displays all objects of the scene with the same white material (clay-like). Handy to check where faces are flipped, combined with the Rendering Mode set to `BF Color` (pink).- **Specular**: displays all objects of the scene with the same reflective orange material.- **Zebra**: displays all objects of the scene with a zebra shader to visualize light reflection breaks.- **Color By Part**: displays each object of the scene with a different randomized color.- **Vertex colors**: displays the colors applied to mesh vertices, if any. If no color is applied, the mesh appears transparent. | | ![Rendering mode](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem378.png)**Rendering mode** | Back-face culling rendering modes:- **Back-face Color** (default): displays back faces with a flat pink color. Handy for spotting triangle faces that are improperly oriented.- **Back-face Culling**: displays back faces as transparent faces.- **Double-sided**: displays the 2 sides of all faces for each object in the scene. | | ![Isolate](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem379.png)**Isolate** | Used to isolate the selection of parts from the rest of the scene in order to focus on it. | | ![Show / no show](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem380.png)**Show / no show** | Use to switch the viewport display between **visible** occurrences (visibility or inherited visibility ON) and **hidden** occurrences (visibility or inherited visibility OFF). | | ![Fit to view](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem381.png)**Fit to view** | Fits camera-view to the selection (or to all objects in the scene if no selection) | | ![Fullscreen](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem382.png)**Fullscreen** | Use to switch to a full-screen viewport display. Click F11 key again (or ESC), or the **Windowed** button to exit full-screen mode (this button is located in the lateral toolbar: move your mouse to the right-hand side of the screen to display it). | | ![Selection mode](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem460.png)**Selection mode** | Used to select the type of geometries that can be selected in the viewport: Part (default mode), [Connected Mesh](../../data-preparation-fundamentals/glossary#connected-mesh), Patch or Polygons.![Selection mode options](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem386.png) | | ![Transform gizmo](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem387.png)**Transform gizmo** | Toggle ON or OFF to activate the transformation gizmo displayed in the viewport, used to move a Part in the scene.Use **Move Pivot Only** to adjust only the pivot point's position and rotation for the selected Part.![Transform gizmo options](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem388.png) | | ![Show B-Reps](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem389.png)**Show B-Reps** | Displays native CAD representation (CAD faces). They are represented as primitive wireframes. | | ![Show Wireframe](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem390.png)**Show Wireframe** | Displays wireframe: mesh edges are drawn in the viewport | | ![Show Shaded](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem391.png)**Show Shaded** | Displays shaded mesh: polygon faces are drawn in the viewport | | ![Show Outlines](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem392.png)**Show Outlines** | Displays mesh outlines information. Outlines are either *CAD patches boundaries* (displayed black by default) or *Lines* (displayed white by default).![Outlines example](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem393.png) | | ![Show Points](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem394.png)**Show Points** | Displays vertices (CAD points, free vertices, point clouds) | | ![Skeleton](/api/media?file=/asset-transformer-studio/2026.5.0/media/NewItem395.png)**Skeleton** | Displays the skeletons of rigged models when existing |
