I used ‘Nishita Sky’ with HDRI in my blender scene.
But when I render it, I can see some of the ‘Lines(?)’ on the background like the photo here.
Why this issue is happening? And how to remove this??
Found out the reason by myself ;(
Simple reason…
I used Sphere object to utilize HDRI. But the default Sphere object from Blender is made of small pieces. (depends on subdivision number). As soon as I ‘auto smooth’ the sphere, this issue was gone.
