Black Hole not black any more (1.3.2 pre7)

Has anyone else noticed that the Black Hole add-on at 61 Cyg A is no longer black? And that the transparent image is now opaque? And that there is no more reflection? At least for me in WinXP / ATI Radeon 9700 Pro.
This is what it looked like in 1.3.1 Final (58 KB) ...

Yes I noticed it, probably the same way you have, via TimMc's new script ?
It's not because of the night texture kicking in is it?

For me reflection is also gone - on ALL reflective objects

There's a black hole at 61 Cygni? Wha??? It's a normal binary system, isn't it?

I just tried this too
And I'm getting the same results
No relfection on the disk
and the centre sphere is iluminating and useing the texture of the disk, when it should be black.
Was working fine before Pre6/7
-----------------------------------------
just done a thorough check, and all nebulas are working fine
all space craft models are reflecting fine
just seems to be the black hole model and Pre6/7 for me.

It's a celestia traditional black hole.

I am the creator of the black.hole add-on.
Iit seems that works fine for me in the last Celestia release, and I have no problems with transparency, I see it the same way that ever, maybe it can be related to the graphic card used ??
I use a Gefirce Fx 5200 128 Mbs maybe in radeon doesnt works well....

Hello High Dark Templar,
Thank you for making this great add-on!
maxim and Terrier have nVidia cards and it is not working for them. It probably has something to do with the mesh code changes Chris has been making. I'm sure he will get it fixed.
Cheers,

Hi all,
I think you shoud know that this line never did work in Celestia
Therefore I use this ssc:
Code: Select all
"Black Hole" "61 Cyg A"
{
Mesh "hole.3ds"
Texture "blackhole.jpg"
# NightTexture "blackhole.jpg"
Emissive true
Mass 3.18e28
Radius 100
EllipticalOrbit {
Period 0.2408
SemiMajorAxis 0.3871
Eccentricity 0.2056
Inclination 7.0049
AscendingNode 48.33167
LongOfPericenter 77.456
MeanLongitude 252.251
}
RotationPeriod 0.002
Obliquity 7.01
#LongOfRotationAxis 228.31
Albedo 0.10
}Don, how realistic is specular reflection on a black hole?
