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.

Creating 360° Panoramic Images

There are three common ways:

1. Capture Using a 360° Camera
