~~SNOW-94~~ Textures keep reloading

Linden Lab Issue ID:	DEV-25723
Linden Lab Internal Branch:	viewer_1-22

Description

« Hide

Repro:

Install 1.21.6 SL
Delete (or rename) your SecondLife settings folder which contains your cache, settings, etc.
Start SL
Set your Texture Memory to 128 MB (this bug also repros at higher memory settings, but takes longer)
Set your draw distance to 256 meters
Set your bandwidth to maximum.
Log into SL
Open your texture console and watch GL Tot. We want to fill up GL Tot, something like 145/168.
Fly around an area dense with textures until GL Tot is full, then stop.

Observe: Your Texture Console will show textures loading perpetually.
In my case, all the textures have DecodePri 904256. The leading 9 indicates these are sculpty textures.

Expected: Texture loading should stabilize and finish.

I'm very interested to hear any repros similar to this where the textures that are reloaded do not have DecodePri starting with a 9.

Interesting. This certainly could create a situation where near textures are not loaded and distant textures are, giving the "loaded out of order" symptom/

No repro - just noticed this happening - harddrive keeps flashing and statistics keep indicating a download for 20 min straight and ongoing.

Cache set to 1gb, video memory set to 128mb. I haven't noticed this before, but then I usually don't stay this long in one place (luckychair with item I wanted, and I noticed on my bandwidth that I continued to download).

Catten saw a couple textures, cfbdd63 and 67f16a6, with DecodePri 1016000.
What kind of texture is 1016000?
Can I track down these textures and determine why they are reloading?

Added a picture of the two non sculpties that kept loading, in case I got the uuid's wrong

DecodePri 1016000 is an "image preview", when you open a texture from inventory or from the edit tool, like http://jira.secondlife.com/secure/attachment/20141/textureconsole.png

After clearing cache and returning the next day, same thing happens at the same place. There are a few new ones it seems though

Tp'ed to 4 sims - let them all load (takes a LONG time) and this happened to two of them. Random places with lots of textures. Also noticed small textures that either didn't load or took forever to do so, but I guess thats a different issue.

Texture priorities table:
BOOST_AVATAR_BAKED = 1,
BOOST_AVATAR = 2,
BOOST_CLOUDS = 3,
BOOST_SCULPTED = 4,
BOOST_HIGH = 10,
BOOST_TERRAIN = 11, // has to be high priority for minimap / low detail
BOOST_SELECTED = 12,
BOOST_HUD = 13,
BOOST_AVATAR_BAKED_SELF = 14,
BOOST_UI = 15,
BOOST_PREVIEW = 16,
BOOST_MAP = 17,
BOOST_MAP_LAYER = 18,
BOOST_AVATAR_SELF = 19, // needed for baking avatar
The boost level is multiplied by 1000 and added to the priority.

You can determine what type of image is being loaded by looking at the 4th/5th digits from the right in DecodePri. 9xxxxx isn't necessarily sculpties, but xx4xxx are, although we use 9xxxxx mostly for sculpties, so you will generally see 9x4xxx. The 1xxxxxx indicates >= BOOST_HIGH

The textures at the top of http://jira.secondlife.com/secure/attachment/21346/screenshot-3.jpg are DecodePri 1012000. The '12' indicates the textures are BOOST_SELECTED. Why are these textures still listed here after they've fully downloaded (the blue [download] bar is full and (Dis) is 0 ) ?

This repro's quite easily with the example Catten stated above.

Repro:
1) Set your Texture Memory to 128 MB
2) Set your Draw Distance to 256m
3) Go to http://slurl.com/secondlife/Raglan%20Shire/36/66/24 , face South.
4) Watch your Texture Console.

Observe: Many of the textures will reload perpetually.

Workaround: Set your Texture Memory to 256 MB, and all textures will finish loading after a minute or 2.

This appears to be fixed for me in Second Life 1.22.6 (108101) as Dan mentioned it does take a minute or 2 for it to settle down tho

Unfortunately the lucky chair located there didn't come up with my letter tho

After clear the cache, and login again, I thought out that it could take a good 3 to 4 minutes of loading all depends on the connection. On the region Heart 1, it took ~ 8 to 10 minutes in 256mb of draw distance.

It's fixed but long time (7 min) to load all the textures

The cause of this appears to be an increased priority of sculptie textures in 1.21.

Here's another way to make a texture load perpetually.

-Rez a box and add this script:

// cycle through all XY10 textures
integer pointer;
list xy_keys = [
        "00e9f9f7-0669-181c-c192-7f8e67678c8d",

-Go to a place where there's no XY10 around you.
-Clear cache.
-Open the texture console (CTRL-SHIFT-3).
-Edit the object.
-ALT-zoom your camera 7 meter away from the object.
-Right-click touch the object.

Observe: a new texture is applied, it doesn't load fully.

-ALT-zoom in very slowly until the desired discard-level (DDis) is zero for the first time. (At about 5 meter from the object)

Observe: The texture loads, then stops. After some time the blue bar jumps back, and it starts all over again.

=======

I've seen this behaviour only on textures with fully transparent parts.
What's happening is, I think, that fully transparent pixels give a texture a lower priority.
At first, the blur of a high discard-level makes a lot of those pixels a little opaque.
But then more detail comes in, more pixels are fully transparent, the texture becomes less important, and the viewer takes a step back.

Still happening in 1.23.4.123908 and Snowglobe 1.0.3 (2537). If the prim has at least one texture with fully transparent areas then that texture will be reloaded over and over.
