[BUG-5978] Rendering problems with Project Interesting viewer #13880

Open sl-service-account opened 10 years ago

sl-service-account commented 10 years ago

Steps to Reproduce

Building, exploring ... everything. It happens all the time

Actual Behavior

Project Interesting may be the most important new feature in SL recently and most of the time it's a great improvement. There seem to be a few bugs that need to be ironed out though:

  1. Close textures going out of focus. Textures on large and close objects - exactly the objects Intersting is supposed to prioritize - have a tendency to shift in and out of focus seemingly at random. This is of course particularly troublesome when I'm working with aligning textures and when I'm trying to find a texture in a texture organizer. But it's rather annoying all the time.

  2. Objects failing to render Sometimes objects fail to render at all.

  3. Reduced Mesh LOD Project Interesting causes mesh objects to stay at the low and mid resolution models at much closer range than they used to. This means that many existing mesh objects that used to be good quality now have to be regarded as broken.

Expected Behavior

I expect textures and objects to render just as well with Interesting as without.

For #2, ref BUG-4752 and BUG-4163

Thanks Whirly! I may have to withdraw #3 too. I've ben unable to reproduce it and it may just have been the same problem as #2, not a general mesh object problem.

Heya ChinRey,

Please can you go to the top menu bar of the viewer, Help -> About Secondlife, click the copy to clipboard button and then paste all your system information into a comment here.

1. Close textures going out of focus.

2. Objects failing to render

Refer to the comments on issue BUG-4163 for the info LL asked for.

Huh, I cant see anywhere where the region grid coordinates are exposed in the viewer UI. Add this script to a rezzed object or attachment and touch it to get the grid coordinates of the region you are on:


default
{
    state_entry()
    {
    }
    touch_start(integer ana)
    {
        string message;
        float xxx;
        float yyy;
        vector corner = llGetRegionCorner();
        xxx = corner.x/256;
        yyy = corner.y/256;
        message ="objects_"+(string)((integer)(xxx))+"_"+(string)((integer)(yyy))+".slc";
        llOwnerSay(message);
    }
}

This will give you the numbers for the correct slc file.

The global coordinates are visible under Help->About Second Life

(global coordinates 276,709.0, 251,079.0, 27.1) Is that what you mean, Whirly?

Whirly Fizzle commented at 2014-05-14T00:34:37Z, updated at 2014-05-14T00:45:51Z

No, these are different coords.

eg) Testylvania sandbox shows "global coordinates 332,659.0, 306,270.0, 21.6" in Help -> About. The grid position coordinates needed for the slc filename are 1299_1196

On Firestorm the grid position displays under Region/Estate -> Region under the Estate ID. On the official viewer I can't find them anywhere

ETA: Found it, Admin -> God Tools -> Region

After spending more time using the Interesting viewer, I am also seeing the "Close textures going out of focus" problem. When this happens, the bias in the texture console just stays stuck on 5 and never lowers, even after teleporting to a pretty empty region. A relog will fix the texture thrashing for a while but it will come back. Before Interesting, I rarely had a problem with texture thrashing.

Demo video: http://www.screencast.com/t/gBS4oijMv On the video, you can see the bias is stuck on 5 and the texture on the path around the pool blurring and sharpening over and over.

I see this JIRA has been dormant for almost a year now while the problem has grown steadily worse. :-(

I'm not sure if this info helps pinning down the cause. Probably not but just in case:

Right now my avatar is standing on an almost empty work platform 2000 m in the air above Coniston: http://maps.secondlife.com/secondlife/Coniston/73/212/2000

So it's obvious the complexity of the scene doesn't matter. Project Interesting texture thrashing happens anyway. There is absolutely no way this scene could even have been even close to filling up my 512 MB texture cache yet the viewer kept thrashing necessary textures to make room for - something.

Watching the texture console, it seemed to me that the list of textures it was loading seemed much longer than the actual number of textures peresent in the scene. So I did a test: I made a copy of the platform, moved it up to 3900 m, removed all textures from it, removed everything from my avatar and stood right in the middle of it. Even in this completely blank and static scene the texture console showed that my viewer was busy loading textures.

It seems obvious that what happens is that the viewer is so busy rendering objects outside the draw distance it doesn't have enough time or resources available to handle the actual scene - exactly the opposite of what Project Interesting was supposed to do.

One final comment. A few days ago Nalates Urriah posted some interesting info in a thread about texture thrashing on the SL forum: https://community.secondlife.com/t5/Second-Life-Server/Zero-spare-time-68-scripts-Run-Frequent-texture-blurring/td-p/2915216/page/3 Seems the cause of texture thrashing has been identified and the problem should be fairly easy to fix.
