Dear all,
The issue I am facing is that in web standalone, the skybox (which is a 360 panoramic image from google street) is disappeared and turned to clear horizon. The second issue is the bizarrely low quality of my material specially the floor material and its reflection which even in indoor spaces you can see the reflection of sky on ground cover. I already searched about the reflection issue and tried to fix it by adding a box just on top of my model so it can cover it, but the reflection still remains.
Thank you for your time.
