Hi!
I need to check. I’ll write later.
I think you need to adjust the Exposure a bit.
Find PostProcess in your scene and find Exposure and change bridgess.
for best quality
Select Camera Rec 360
Activate option Quality(Experimental)
You used Realtime or Static picture?
Change Texture Size to 4096 or better (5000-6000)
Output size example 10000x5000 or 10000x10000 and change aspect ratio in any image editor. If aspect ratio 1:1 -> better for pixels.
I need checked color from camera 360. I write to later.
