3D Models

Sharp Stock deeply supports mainstream 3D model formats used in game development. Artists, programmers, and planners can directly review model details within the asset library without opening heavy professional modeling software or engine editors.

1. Supported Format Standards

The system natively supports major 3D exchange formats:

• FBX: The industry-standard 3D exchange format, widely supporting skeletal, animation, and material information.
• GLTF / GLB: Efficient, lightweight modern universal transmission formats, a top choice for Web and cross-platform game development.

2. Interactive Preview Features

360-Degree All-round Observation

After selecting a 3D model asset, the right detail panel will automatically activate an interactive viewport:

• Rotate: Hold the left mouse button and drag to inspect the model from any direction.
• Pan: Hold the right mouse button and drag to move the focus point. The middle mouse button can also be used.
• Zoom: Hold Ctrl while scrolling the mouse wheel to inspect details or zoom out. Scrolling without Ctrl continues to scroll the surrounding page.
• Reset View: Click Reset View in the toolbar, or focus the viewport and press R, to restore the default framing.
• Axis Gizmo: The X, Y, and Z axes are shown in the lower-right corner. Positive endpoints use the standard axis colors, while negative endpoints use lighter matching colors. Click an endpoint to switch to its aligned view.
• Expanded Preview: All interactions, render modes, and shortcuts remain available in expanded preview.

Rendering and View Helpers

The compact buttons in the upper-right switch render modes. Hover over or focus the i button in the upper-left to see the complete interaction guide:

• Lit: Shows the original materials, textures, and viewport lighting for checking the final appearance.
• Unlit: Keeps colors and textures without viewport lighting, making texture details easier to inspect.
• Untextured: Hides textures while retaining lighting, which helps reveal silhouettes, surface form, and normals.
• Wireframe: Displays mesh edges for a quick review of mesh density and topology distribution.
• Viewport Background: The 3D viewport uses a neutral gradient that adapts to the light or dark theme, keeping it visually distinct from the checkerboard used for transparent images.
• Helper Grid: Click the grid button or press G to show or hide the ground reference grid. A red X-axis line and blue Z-axis line cross at the grid origin to make ground orientation clear.
• Auto Rotate: Click Auto Rotate or press A to toggle turntable playback. It is off by default so it does not interfere with manual inspection.
• Model Animation: When a file contains animation, a Play/Pause button appears. The previewer plays the first animation clip by default.

Smart Material & Texture Recognition

The system automatically analyzes and attempts to load textures associated with the model. If texture files are located in the same directory as the model or in a standard textures subdirectory, the previewer will automatically present a realistic rendered effect with textures.

3. Organization & Management Suggestions

• Resource Storage Standards: We recommend storing model files and their accompanying textures in a unified folder so the system can precisely associate textures.
• Performance Tagging: Use the tagging system to label models with "High-poly/Low-poly," "LOD levels," or "Belonging Character" to achieve rapid resource retrieval.

4. Common Troubleshooting

• Why is there no texture when previewing a model?
  • Please verify if texture files are in the same folder as the model or in the textures directory. Also, check if the relative paths recorded during model export are correct.
• Is animation preview supported?
  • You can play or pause the first animation clip stored in the model. Animation selection, a timeline, and frame stepping are not currently available.
