 Description  « Hide
I am seeing only two local lights active in the newest 1.19.4 viewer. I was able to see all six local lights in the previous non-windlight client so I know my card can handle it. Tried placing six prims in sandbox with no other local lights around. Only two of the six will light up, whichever the avatar is closest to. The sun and moon light does not seem to factor into this. This might also explain the flickering local lgihts that another Jira entry was talking about. I have tried changing the performance settings from the lowest to ultra. Have installed the latest ATI catalyst software. No controls for lighting in catalyst sw.

OK I did a little more testing. I set up 6 light sources with different colors.

In Dazzle (this is the older non-windlight dazzle) viewer, avatar and prims are colored by all 6 lights.

In the 1.19.1.4 viewer,

Basic shader on, atmospheric shader on: prims colored by 2 lights, avatar colored by 2 lights.
Basic shader on, atmospheric shader off: prims colored by 6 lights, avatar colored by 2 lights.
Basic shader off, atmospheric shader off or on: prims colored by 6 lights, avatar colored by 6 lights.

I see boxes for all the lights when enabling the lights info display.

Maybe related but I have noticed that i am having problems with local lighting - no matter what graphics settings - but when i am at my studio i tend to run with Basic Shaders on, atmospheric off, and sky gammed turned down very low, as that tend to give more predicatble results (not always though).

The problems are :

  • Single lights at full intensity don't always light the scene or the avatar sufficiently (Radius set to 10m, Fall off set to zero).
    Turning a second light on - mostly (but not always) will make the first light have a strong effect) - like the sum is greater than the two parts. Turning either light off will result in another dimly light image.
  • Intensity does not seem to work correctly - I had one light that dimmed between Intensity (1.0 and 0.8) - below 0.8 the light was effectively off - and if intensity went below 0.8 then the insity had to be reset back to 1.0 to get the light to "work" again. The 0.8 boundary is variable though - another light showed the same boundary problem - but with its boundary seemingly at 0.5 intensity.
  • Some lights will fail to light the scene at all. with a set of 6 identical lights (not all on at the same time) - occassionally some lights (one in particular more than most) will simply fail to provide any light on the Scene or avatar, regardless of intensity. Deleting that light, and replacing with a copy of one of the others, at the same place as the first will the provide a working light. It is almost like the first light goes stale in some way - but all scripts etc still work - and the lamp "bulb prim" does everything as expected when the light is on, just no light is emitted on surfaces or Avatar.

I will try to capture more information on the lights info when next in world

Seeing 2 lights as well. Atmospheric Shaders. On, 2 lights. Off, 6 lights.

Seeing 6 lights, here, with all shaders on and all the graphic settings maxed out.

Linux, Nvidia 7600GT, latest Nvidia beta drivers (173.08), Cool SL Viewer v1.19.1.4 release 4.

Seems to be a hardware related issue: the Windlight rendering engine is very demanding towards the graphic cards, so it's not really a surprise that trade offs are to be experienced on lower end GPUs...

Hi Bree, Have you tried this in the latest RC? Also, are you setting yourself to Midnight?

Bree Giffen added a comment - 25/Jun/08 07:59 PM - edited
OK. I've tested this again. I have the 1.20.11 RC viewer that I just upgraded today. I also have the latest June 18 ATI drivers for my Radeon x1300. I am set to midnight.

Basic shader on, atmospheric shader on: prims colored by 2 local lights, avatar colored by 2 local lights.
Basic shader on, atmospheric shader off: prims colored by 6 local lights, avatar colored by 2 local lights.
Basic shader off, atmospheric shader off or on: prims colored by 6 local lights, avatar colored by 6 local lights.

By 'colored' I mean that I can see the light actually lighting up the prim or avatar.

Turning on the info display for lights shows all lights are active. I see a white box around each light source and a yellow box for the light radius.

Looks like the same results from the last time I tested this.

This bug has been going on for so long..

I don't even use the Windlight sky and water anymore, unless I'm doing a photoshoot. The ability to see the landscape, as lit by it's designer, is more important than "eye candy" water and sky.

I've made a little video to show the problem:

Does it help to have info from people who see all the lights with all shaders on?

After seeings Winter's video in a forum thread today, I tried the same and see all the lights and all their colors on my body (even wore white).

Seeing a similar situation on my iMac as well, but with this wrinkle:

If I have basic shaders selected, I lose many/all local light illuminations. If basic shaders aren't selected, local lights are visible.

Set environment to midnight.

See comparison screen shot for setting/light effects (local lights visible with shaders off, invisible with on).

Snowglobe

Not fixed with: Snowglobe 1.1.0 (2554) Jul 22 2009 18:50:15 (Snowglobe Test Build)

Also...some had suggested turning off Atmospheric Shaders...no difference with that, or any other Graphics preference I could find.

Someone please light a fire under Runitai Linden.

Two local lights is just ridiculous. Six was marginally better, but still very limiting, What is the holdup in adding even more local lights? Is there some technical problem?

Come on!


TigroSpottystripes Katsu added a comment - 23/Jul/09 03:15 AM
the OpenGL specifications allow for a minimum of like 8 lights, most video card manufactures never go above the minimum required except in rare cases, SL has a couple of the slots hardcoded to be used by environment lights, the remaining are what is used for prim point lights

a bigger number of lights can be achieved, but they won't be hardware lights, or actually, they won't be more lights, they will be the same 8 lights, moved around and re-processed for the things they affect, all effects being composed and rendered together after each individual group has been done (or somthing along those lines). I'm not sure what is the minimum hardware requirement for performing this trick, have been given conflicting answers int his regard

From my understanding, they kicked the limit even lower thant he minimum amount of lights avaiable from the hardware because they think that with all the performance issues SL got, video cards that aren't top-end will have a significant performance loss with more local lights being used, seems like the same style of thinking that brought us disappearing prims and many other issues....


pulseburst flow added a comment - 13/Aug/09 03:39 PM

See new issue: https://jira.secondlife.com/browse/VWR-15114

Graphic features, such as local lights, are unnecessarily restricted on graphic cards/platforms that can support them due to erroneous settings files. Please fix for next release and document.


Jopsy Pendragon added a comment - 28/Dec/09 09:23 PM
Some of the alternate viewers have resolved the two light problem.
