A visit to a Sister Planet

Sister Planet
Sister Planet LEA27

Sister Planet is Kimika Ying’s latest installation at the LEA, and given I enjoy science-fiction and have a bit of an interest in space exploration and astronomy, it’s one that should be right up my street. It takes as its theme what is often referred to as Earth’s “sister planet”, Venus (so-called because it has a similar size, gravity, and bulk composition to that of Earth). But what is presented here is not the Venus known to science today, but rather the Venus science-fiction once presented to us, even as late as the 1940s: a warm, wet planet with verdant rainforests existing under its heavy clouds.

Here, then, is a world from an alternative universe, where human beings have started to explore, establishing a small base on the edge of a verdant rainforest surrounded by hills and strange rocky outcrops, and above which the odd volcano or two pokes its snout.

The forest itself is both strangely terrestrial in nature, and also very alien, while the base camp mixes parts of old rockets with pot-bellied units sitting on spindly legs. Above the trees and beneath the clouds, strange green creatures fly, often chasing large seed pods which periodically drift up into the sky. The creatures have no wings as such, but propel themselves by a sudden spinning motion, which also gives them their name; while under the canopy of trees, other strange flora and fauna reside.

Of course, we now know that all the early hopes of Venus really being a sister planet to Earth have been well and truly dashed; the planet is in fact one of the most inhospitable places in the solar system; yet the old science-fiction stories might, under other circumstances have been right. The orbit of Venus sits just beyond the inner edge of what is called the “circumstellar habitable zone”, or “Goldilocks zone”, the region around a star within which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their surfaces, and thus possibly offer conditions suitable for the advent of life. As such, an exploration of what / if with regards to Venus perhaps isn’t in appropriate.

Sadly, however, I’m not sure that this installation succeeds in doing that; while the blog that  accompanies the installation makes for good reading, chart as it does both the development of the idea and Kimika’s leap into mesh content creation, I’m not sure it achieves anything else. Certainly, as one who very much enjoyed at appreciated Kimika’s Oceania Planetary Park, which formed a part of the fifth round of LEA AIR grants, I came away from Sister Planet somewhat disappointed.

SL project updates week 44/2: server, viewer, issues

Darkwood, for a Calas Galadhon Halloween
Darkwood, for a Calas Galadhon Halloween! (Blog post)

Server Deployments Week 44 – Recap

As always, please refer to the server deployment thread for the latest information and updates.

  • On Tuesday, October 28th, CDN support was deployed across the Main channel, meaning that the entire grid now utilises the Highwinds CDN for texture and mesh fetching. As the 130 regions deployed to the Snack channel were all originally from the Main channel, they have been reabsorbed into that channel, and Snack has once again be dissolved
  • On Wednesday, October 29th, all three RC channels received the same server maintenance project. which includes some minor improvements, which were described by Maestro Linden at the Server Beta meeting on Thursday, October 30th, as, “just some code cleanup and some extra optional debug logging.”

SL Viewer

On Wednesday, October 29th, the Lab promoted the HTTP Pipelining RC viewer (version 3.7.19.295700) to the de facto release viewer. As I’ve noted in previous blog posts, this viewer:

  • Can issue multiple asset fetches on a connection without waiting for responses to earlier requests. This reduces the impact of a user’s physical location on scene loading and generally improves the experience for everyone
  • Includes significant improvements to inventory folder and item fetches, which can markedly decrease the time taken for inventory to load.

All other SL viewer remain as per my Current Viewer Releases page.

Issues and Problems

Mesh Loading Issues

There have been mixed reports of mesh loading issues, which may or may be linked to some long-standing issues with mesh attachments. During the Server Beta meeting on Thursday, October 30th, the issues of mesh items which should be cached by the viewer being slow to load, don’t show up at all or show up with a low LOD, requiring a relog. Interestingly, the meshes can appear correctly when using one account, but not with another, either though both accounts are drawing from the same viewer cache.

Whirly Fizzle noted that there is a potential (and equally weird) fix for odd mesh loading issues, commenting:

There’s a weird mesh loading issue (not new) that’s “fixed” by deleting a certain per account file. I don’t even know why it should even work but it does. Sometimes a certain mesh gets stuck and will not render for a certain account. Relog doesn’t fix it & neither does a cache clear. You have to delete texture_list_last.xml in the per account settings files.

Texture Load Issues

There have been a couple of reports of texture loading issues which are still under investigation.

In the first, there have been  some reports that textures are getting stuck when “half loaded”, so that they remain blurred or may fail to render. It’s not clear how widespread this issue is, or whether it might be related to BUG-6382, although this is also unclear.

In the second, one content creator has reported customers are suddenly having issues with a HUD-based system for changing the colour of their shoes. When used, the textures rez very slowly, or the shoes get stuck as grey for up to 5 minutes at a time, or get stuck at a 1st level load until the wearer teleports or relogs. This is apparently a completely new behaviour with the shoes in question, and it appears to be exacerbated when using the HTTP viewer.

AMD Catalyst™ 14.9.2 Beta Woes

The latest AMD Catalyst™ 14.9.2 Beta drivers will not render rigged mesh unless hardware skinning is disabled. The current workaround is to either disable hardware skinning (which is not ideal when it comes to rendering mesh in general, and ALM features like materials will not render) or to remain on / roll-back to the 14.9.1 beta drivers if the problem is encountered. See BUG-7653. As was mentioned in the Server Beta UG meeting, this could be particularly confusing to new users running AMD GPUs and who are using the Lab’s default mesh avatars.

E-mail Communications Issues for In-world Objects

A further JIRA has been filed in respect of e-mail communications with in-world objects hanging for no readily apparent reason (see: BUG-7554). similar issues have been reported in the past (although this one has a publicly viewable report), and Caleb Linden is currently poking at things.

From a Little Village a Little Town does grow…

Little Town
Little Town

In March through April 2014, Cica Ghost has a charming installation on the region of Caramel. Called Little Village, it was a marvellous collection of whimsical little houses with wobbly chimneys, huddled together in groups or standing alone, some on level ground, others precariously straddling little hills, and about which I blogged at the time it was open.

Little Village may have gone from the virtual world at large, but on Thursday, October 30th, Cica opened Little Town, which might be regarded as Little Village all grown-up. And it is another absolute delight of the quirky and the fun.

Little Town

The buildings here are “life-sized” (in avatar terms) when compared to Little Village, but they all display the same higgledy-piggledy charm. Most are gathered around a town square atop a large flat hill in the centre of the region, although several are scattered more widely afield.

Here you will find tall finger-like houses, their once-bright paint a little faded and warn, sharing space with other structures of unknown intent. Pipes and tubes and horns twist and run between buildings or point skywards while trees and bright patches of flowers add further colour to the scene, as bright balloons drift about the place. There’s even a building that looks peculiarly like a gigantic coffee pot, a pipe-like handle on one side, and the spout formed by a another pipe as it twists it way to connecting with conical neighbouring structure.

Little Town
Little Town

While the inhabitants may be conspicuous by their absence, this is a town that is very much alive in its own way; there is motion everywhere as windmills turn in the breeze, cogs and wheels rotate, horns stretch and contract from rooftops, strange spherical objects push their way through pipes; even the odd rooftop rises and falls as if breathing slowly, all of it serving to add a depth and further charm to the whimsy on display.

Getting around is easy: wide steel roads, heavy with rivets, offer various routes around the town and its outlying areas, while steps down from the hill provide access to those places off the main roads, and of course, visitors are free to wander where they like. For those not into walking, there are cars available from a rezzer near the cinema cafe, while a gift giver near the landing point will present you with Cica’s Flying Ventilator, if you fancy getting a bird’s-eye view of the town. And speaking of the cinema – do be aware that some of the buildings can be entered as well – there’s even a cage where you can do Airkix-style “skydiving / flying” :).

Little Town

Should all the exploring tire you out, Cica has provide a trio of floating beds in the south-west corner of the region, where the weary can rest a while. The field over which the beds floats is also home to Cica’s little flower shop, where you can purchase sets of the flowers which can be seen around the town and region, as can copies of the two mechanical birds sitting under a nearby parasol – proceeds from sales doubtless help towards keeping the sim open.

Given Little Town involves so much motion, something no always captured in a simply snapshot, I’ll leave you with a video of the town in the hope it’ll encourage you to pay a visit and share in Cica’s whimsy!

Lab asks: how is SL for you?

Just Another Tequilla Sunrise, Isle of Love; Inara Pey, October 2014, on FlickrSL should be looking and feeling a lot better for many of us as a result of recent work by the Lab – how’s it going for you? The Lab asks you drop them a line in the forums or via Twitter (image: Just Another Tequilla Sunrise, Isle of Love (Flickr) – blog post)

Following-on from the grid-wide deployment of CDN support and the promotion of the HTTP pipelining viewer as the de facto release viewer, the Lab has blogged about recent improvements to Second Life, finishing with the question “how is it for you?”

The blog post, entitled, Performance, Performance, Performance, opens thus:

Has Second Life seemed a bit faster for you lately? Improving performance for all Second Life users has been an important focus for us at Linden Lab, and we’ve recently seen some great results from several projects that should make your Second Life experiences faster, smoother, and more reliable.

It goes on to make fair mention of the CDN / HTTP work, noting:

Faster Texture & Mesh Loading
The entire grid is now using a CDN service for textures and meshes. This change means that textures and meshes should load more quickly, particularly for those who login to Second Life from places that are far from our US data centers. Our testing showed dramatic improvements: average download times for textures and meshes have been reduced by more than 50% on average, and the improvement is even more dramatic outside of North America.

Quicker Viewer-Server Communications
Another way we’re enhancing Second Life performance is through our HTTP project, which improves the way your Viewer communicates with grid services. With the HTTP Project Viewer out now, the faster content download times you’ll see thanks to the CDN change get even better – we’re talking 80% faster!

For those who may have missed news on the HTTP pipelining viewer and the CDN support, you can catch-up with things via a couple of posts on this blog: SL project updates week 42/2: Monty’s HTTP update and the HTTP pipelining viewer, and HTTP pipelining viewer reaches release status as CDN support is grid-wide.

Mention is also made of the recent Group Chat updates (work is still continuing on this, and you can get updates via the Group Chat tag in this blog).

However, perhaps the most interesting aspect of the blog post is the news that there have been some significant infrastructure updates with the SL Marketplace, which appear to have slipped mention through other mediums such as the var UG meetings. Here the blog post notes:

Speeding Up the Marketplace
If you visit the Marketplace today, you should be seeing a much snappier experience than in the past. We recently deployed infrastructure upgrades for the Marketplace, and the site has since shown some of the best performance we’ve ever seen from it. Even during peak usage periods over the weekend, when in the past performance would degrade, we’re seeing response times that average 70% faster and page load times that are 30% faster than before the changes.

I’ve not used the Marketplace of late – although I have been covering the upcoming Viewer-managed Marketplace (VMM) changes that will be occurring in 2015, and which the Lab is currently gearing-up for, along with merchants and TPVs.

So have you noticed changes and improvement in your Second Life experience? If so, then why not follow the Lab’s request:

So, How’s Second Life Performing for You?
Performance improvements are generally behind-the-scenes work, and we know it’s not always as exciting as rolling out a new feature, but these changes directly impact all our Second Life experiences and our daily lives in-world. We hope you’re starting to notice the effects of these improvements – if you are, please let us know in the Forums, on Twitter, or however you prefer.

Note that is let the Lab know – not me (although general views are always welcome here, they might not be picked-up by the Lab)!
