This might be related to the jaggy 32 bit textures Im seeing here too: https://jira.secondlife.com/browse/VWR-3197

Ok I just found out that disabling IMPOSTERS fixes this. Are the shadows accidentally becoming imposters?

Torley Linden added a comment - 27/Nov/07 01:54 PM
I checked with Runitai Linden to confirm – foot shadows disappear when avatars become impostors, so no, they don't become impostors.

"Won't Finish", because Runitai checked this out and it looks like Z-fighting ( http://en.wikipedia.org/wiki/Z-fighting ); not a simple solution to that.

Actually this isnt z fighting. The foot shadow does this when the avatar is NOT an imposter yet... so something else is going on

Sorry meant to say more. I get this problem even on very close zooms

OK a bit more info after closely looking at the foot shadows. They actually change appearance. Tha alpha mask seems to be removed and the shadow image becomes very pixelated. Is this possibly related to 32bit/alpha optimisations?

This issue was resolved as "Needs More Info" during our batch cleanup because it was set as affecting First Look: WindLight. On the Issue Tracker, we've noticed many duplicate issues and issues that lacked actionable info or were already fixed.

WindLight recently "graduated" from a "First Look" technology preview to Release Candidate status – nearing inclusion in the main viewer with your help! So, "First Look: WindLight" does not exist anymore.

More info and how to download the RC viewer: http://blog.secondlife.com/2008/03/06/new-release-candidate-viewer-1191-rc0-available/

If you've verified that this issue is still a problem in the newest Release Candidate, here's what to do next:

(1) Search the Issue Tracker to make sure it isn't a duplicate of an existing issue we know about. If it is, link it as a duplicate using the "Link this issue..." link on the left. You can learn more about searching by watching this video tutorial: http://www.youtube.com/watch?v=SAlXK5hSVMc

(2) Reopen the issue and BE SURE to update the "Affects Version/s" to the correct one, most likely ONLY "1.19.1 Release Candidate". However, if this bug affects the main viewer (1.19.0 as of this writing), then DO NOT set it to an RC version. Only set it to 1.19.0 instead. Be as specific with versions as possible – there's generally no need to set multiple versions, as it tends to dilute and confuse where a bug originated.

(3) Add any other relevant details that would help us fix it. We can't stress the importance of a "solid repro" enough – a reliable series of steps to make a bug happen reliably.

(4) Come and attend our inworld bug triages, where you can meet with Linden Lab employees to look at, verify, and expedite bugs for fixing. More info @ http://wiki.secondlife.com/wiki/Bug_triage

Thank-you for helping us improve Second Life!

okay if you look are it carefully is it a silhouette of someone silhouette. I appears to happen close to the distance where the AV is going to be come an imposter. once the Person becomes and imposter the foot shadow goes away. it is also not the silhouette of that person at which the foot shadow resides.

re opening issue with more info.

gearsawe stonecutter added a comment - 10/Nov/08 06:15 PM
After further observation. The silhouette in the shadow which is that of the furthest person away from your camera if you have avatar impostors on. Very weird?!
