It works perfectly for me.
Oops. Interesting. Just checked with a fresh installed 0980 and I see the effect in Sag A*.
VoyagerX, could you please attach your
se.log file? It's located in your
SpaceEngine/system/ folder.
Edit: In my case, one of the addons is causing the issue. [s]Which one, I don't know, I simply moved the entire "addons" folder elsewhere[/s] It appears to be an Interstellar addon (Interstellar-v2-980.pak), I moved it out of Addons folder and the effect is reinstated.
In fact, that's what
DoctorOfSpace said about this mod:
This is scientifically inaccurate and was asked for by someone who I can't remember. It makes all accretion disks in the game look similar to the one in Interstellar. This removes the doppler effect so the accretion disk is evenly lit, the sky will only grow in brightness but not shift blue, and the radius of accretion disks is smaller.
