[Opensim-users] Stars in night sky in OpenSim are shapes rather than dots?

[Tom]

np. I adjusted the viewer settings in Firestorm (Edit Sky Preset, Below Sun and Moon Settings is Str.Brite). The sky preset shortcut is next to the address bar.  I know of no adjustment at server end and suspect that this is purely related to the rendering engine within the viewer. That does not mean that there is not one. It may be possible to use lightshare to manage your visitors windlight settings. This only works with some viewers though.

>> You are right. I do not think that this is a problem though. I checked some photos of stars ... (Jodrell Bank) and shapes seem more realistic.

>> I fiddled with the environment editor under Sun and Moon Settings StrBrite. If I increase the star brightness in both SL and OS there comes a point where they look like shapes as per Ai's photo. OS looks a bit more shapely but it is difficult matching skies. I am using an NVIDIA GeForce GT 650M and Firestorm 4.3.1.31155 15-inch, Mid 2012 MBP. At 2.00 (nice dots) becoming more shapely with increasing brightness.

>> I spoke to Linden Labs about this a long time ago, I believe this is a driver issue, do you get same results in Second Life, at the time I noticed this i was having same problem in SL and OpenSim, and one of the Lindens seemed somewhat unaware of the issue, and after asking others about it i recall the answer being its a driver problem with video cards. If you could test in Second Life that would be great.
