Quality of the 360/2D photo

Question:

What photo quality should I use to incorporate them into scenes without having visible pixels?

Answer:

Image formats compatible with Sphere are “.jpeg” and “.png”. About the size:

• For photo panoramas (360), we recommend an 8192 x 4096px resolution
• For other photos (2D), it depends on your images. However, it is preferable not to go over 512px and avoid images with transparency for better fluidity.
