So I'm a little puzzled. I decided to add a new galaxy to my new star field generator. But, I immediately noticed something strange. The Simple Shape Shader when rotated on X by 90, to put it on the horizon (just to rest rotating) it repeats on the back side of the sphere as well. I was puzzled why I was seeing the same thing when I switched to 180 rotation, because it literally is the same thing on the other side. Is this normal? Can I not have this happen? Or?
Maybe clamp the output so negatives are out?
Hmm. Nope. An actual PF shader isn't doing the same shape on the other side. Next I'll try a manual function ellipsis.
Mask by distance (clamped Z) shader then....
I think it's because of the SSS at 0,0,0 to be rotatable. So it's being read from either side
Is it rendering like that or just showing up like that in the VP?
I have had similar issues with sun lights showing up in two places. Renders were fine though.
Check your default shaders specular settings.
There is no default shader, it's all no-alpha except the stars, and glows which are from a masked surface layer with a Alpha background (for a post fx mask). The rest is just luminosity glow.
It's in the renders too. The example is a spherical render showing both sides of the BG sphere.
