Best Practice on Optimization

1. Set an Appropriate Color Mode

• Use the RGB color mode to detect color shift issues in real time.

• When exporting, make sure to enable “Color Space → Convert to sRGB.”

• After exporting, always check whether any color deviation is present.

2. Choose an Appropriate Image Size

• To ensure sufficient clarity for background display, we recommend a resolution of: 4096 px × 2048 px

3. Set an Appropriate Image Resolution

• Recommended resolution: 72 PPI

4. Select the Appropriate Image Format

• If the image does not contain transparency → Export as JPG or JPEG.

• If the image contains transparency → Export as PNG.

⚠️ Note: In current 3D interactive scenes, transparent areas will appear as solid white (background rendered as white).

5. Optimize Image Compression

• We recommend using TinyPNG for compression and optimization.

• Upload and compress your images directly using the link above.

6. Use Suitable Pixel Dimensions

For best performance, set image width and height to a power of two, such as: 4096, 2048, 1024, etc.
