The "inside" part of the material stops displaying UE5

Hi.

I have a space scene with galaxy “skybox” made from sphere with two-sided material. Mostly it looks great, but in some circumstances (in editor and in game) when i “fly” away from my planet (in 0,0,0) and with some camera angles, “inner” side of my galaxy stops displaying (becomes transparent). What i’m doing wrong? )

(Regular galaxy)

(A little move with camera - transparent galaxy)

The pictures aren’t showing…?

Yeh, sorry. Fixed.

I think you’re just moving outside the sky sphere. Have you tried scaling it up?

Yes, i,ve tried. I,m absolutely inside sphere.

What’s the material graph like for the sphere?

Simple enough. Have you tried removing the sun disc node ( for now )?

Yes. Nothing changed. And if i disconnect sun disc node - skybox began to block it, but when it became transparent I see the sun.

No idea, I’m afraid…

Some aditional information: situation is worse, then I thought.
I’ve tried to place some objects in frony of camera in “dark” mode (when galactic material become transparent). So - in this position i don’t see nothing at all, but sun. Objects are enabled and exists on scene and i see them with other different camera angles.

Really not sure what’s going on. Do you have a directional light?

Yes. In conclusion - i just made my scene much smaller and strange effect fades away. I don’t know still, what it was.

Ah, if you make things very big, you get all sorts of problems…
