3d Model Upload and Adjustment

Where to Upload Models

Scene Editor — Upload Assets

• Local Upload: Upload files directly to the asset library. The system will run an intelligent check on the model — some assets may require uploading via the Content Editor instead.
• Content Editor Upload: Open the Content Editor to preview and adjust the model, then click Save to save it to the asset library and generate a thumbnail.

Supported Upload Formats

Supported model formats: GLB, GLTF, OBJ, FBX. GLB format is strongly recommended. For GLTF, FBX, and OBJ files, package the model together with its textures into a single ZIP archive before uploading.

Supported image formats: JPG, JPEG, PNG. Maximum resolution: 2048 px.

Recommended upload file size: ≤ 10 MB; optimal: ≤ 5 MB; hard limit: 30 MB.

Adjusting in the Scene Editor

Assets

Newly uploaded models will appear at the top of the asset library. Drag them into the viewport on the right to add them to the current scene.

Key Settings

The Scene Editor controls adjustments that directly affect the end-user experience. There are two critical settings to configure first.

Rendering Engine Version

When creating a new scene, you'll first be asked to select an engine version. This can be changed later, but should be adjusted based on the feature support shown below.

Version	Supported Features	Platform Support
v1	PBR, Unlit	Web, Wechat Mini-Program
v2	PBR, Unlit, Clearcoat, Anisotropy, Sheen, Specular, Transmission, IOR, Dispersion, Iridescence	Web

Tone Mapping

Type	Effect
None	No tone mapping applied. Highlights are prone to overexposure and color bleeding.
Linear	Uses linear mapping. Visual result is the same as None.
ACES	Uses ACES tone mapping. Reduces highlight overexposure and produces smoother highlight roll-off with more retained detail, but introduces a slight color shift.

Lighting Adjustment

The scene includes a default light setup and HDRI by default. You can switch to a different built-in HDRI environment and adjust based on the desired result. You can also upload your own custom HDRI. If you want the scene to be lit entirely by the HDRI environment, set both the ambient light intensity and directional light intensity to 0.

Model Adjustment

When a model in the scene is selected, a toolbar appears above the viewport with quick tools for adjusting the selected model.

Outline

Apply an outline effect to the model.

Smart Optimization

1. Mesh Simplification: Reduces polygon count by a specified percentage.
2. Animation Optimization: Reduces the size of animation data.
3. Textures: Optimizes texture file size based on maximum resolution and compression quality.

Poivt Edit

Modify the model's pivot point.

Note: This adjustment is calculated based on the model's overall bounding box. If no change occurs after adjusting, return to your DCC application to make the correction there, or check whether the model was exported correctly.

Custom Animation

Assign a custom animation to the model.

Material Edit

Jump to the Content Editor to adjust the model's materials.
