  1. Wow, now we have sale and leaseback arrangements on SL. Just like RL. (Silicon Graphics did a deal like that with Goldman Sachs for what is now the Google campus. It worked out very badly for SGI, which was desperate for cash at the time.)
  2. Thanks, Luca. That's what motivated me to work on this problem. You can see that the last movement update, the one that gets extrapolated, is bogus. That car was going along smoothly. If the predictor kept it going in the viewer in the same direction with the same rotation while the region crossing processed, it would look OK. But it's clearly extrapolating from bad data, and the car flies into the air and rolls. Or seems to. That's a viewer-created illusion. It leads people to make frantic steering corrections. Then they crash. The "Stop" setting stops that, but rather abruptly. This is embarrassing for Linden Lab. Really. They've had that bug since at least 2013, and haven't been able to fix it. A clip like that really shows how bad this is. Modern video games do not do things like that. This is the sort of thing that gets "Your game sux" comments from new SL users.
  3. You are completely right. When I zoomed in, I got the down escalator. No bug. My bad.
  4. I'm the author of the "stop at region crossing" code. Technical background here. Short version: There's a fundamental problem, that region crossings take time, during which the object is frozen in place. And there's a bug; the very last update sent to the viewer by the sim that's giving up the object has velocity and acceleration info which contains poor quality data. Those are both server side problems. Ones LL is unable to fix. We can try, in the viewer, to hide both problems from the user by guessing what the data ought to be. Available guessing approaches are Just extrapolate blindly what was happening before the object left the sim. (Old behavior, and Firestorm in "Predict" mode). OK for slow boats, terrible for fast land vehicles. Stop the object on screen hard during the region crossing. (Firestorm in "Stop" mode.) The pause is annoying but there is no bogus motion on screen. Drivers like this, sailors do not. Extrapolate blindly, but with a time limit (Current LL viewer behavior.) Prevents the worst effects while keeping the sailors happy. Evenly distributes the misery. I agree with Luca on this. Start out new users in "Stop" mode, which is understandable, and tell sailors how to get "Predict" mode for a peaceful slow sailing experience. Or at least set the default timeout in the Linden viewer to something small, like 100ms. (I've done about as much as I can do until LL fixes some server side bugs. Fancier viewer side prediction algorithms might help, but fixing the bad data that comes out of the sims would help more. Meanwhile, if you want to experience a smooth drive, set "Stop" mode, get a car from one of the demo rezzers of the car builders in Burns and drive around Heterocera. You will have smooth region crossing experiences, but a momentary hold at each crossing. I'm done with this for now, until LL fixes some bugs. I once said to Oz Linden at Server User Group, "You guys fix the sim side problems and we'll take care of the cosmetics". Between what viewer devs can do in the viewer and what vehicle builders can do in vehicles, we can make region crossings look and feel good. But we cannot make them not break. That's on LL.)
  5. This all mesh object has two LOD models, and the lower one is different enough from the close-up that this isn't the problem. (I'd post a picture, but Vallone sim is offline right now.)
  6. That might make sense at distance. But this is reversing in close-up. The zoomed-out version is correct. The zoomed-in version is wrong. Knowing that the viewer changes animation speed with distance is useful. Now we know where to look for the bug.
  7. Are you outside the US? A friend was locked out for weeks due to LL not properly processing funds from a bank in Scandinavia. Despite letters from the bank to LL, the problem took weeks to clear up. She lost her oceanfront parcel and her in-world store was out of business for weeks. LL really needs to get properly plugged into the major non-US payment systems. And no, that does not mean making people use PayPal. That's Tilia's job.
  8. Some keyframe animations look wrong at some zoom levels. Known bug. Tends to show up for distant rotating signs. It also sometimes affects my escalators. Here's a really strange situation. When you zoom in, the stair motion reverses. Strangely, it reverses for both the angled steps, which are keyframe motion, and for the flat steps at the top, which are simple texture animation. This is Firestorm, but it's known to appear in the Linden viewer, too. I can't update the JIRA because the bug report was merged into another bug, which I can't comment upon.
  9. "Networked advertising" in SL does not seem to be doing well. Much of the ad space is selling - ad space. In back of the Linden info hub in Ungren is a huge wall of ad boards. Most are non-revenue. There are some political signs, some public service announcements, and a big ad for an area that went out of business last year. Signs over 110 meters high, over 200m high if you count the floating purple cube with an ad. 135m wide. And moving arrows on Linden land. There are some huge billboards in Corsica, based in tiny 4x4m parcels. Selling ad space. They're so tall that, driving by, you just see the post; the sign is too high up. As a business area, this looks dead. Although the ugliness lives on.
  10. Unclear. Linden Lab says that. Whether the SEC and the IRS would agree is something else. LL is desperately trying to avoid having to register Linden Dollars as a security. That may or may not succeed. The SEC is regulating cryptocurrencies more strictly, and they are fed up with the issuers running off with the cash. Properly, LL should request a no-action letter from the SEC, like this one: https://www.sec.gov/corpfin/pocketful-quarters-inc-072519-2a1
  11. Location, location, location. You want some barren hillside in Corsica, there's about 10 whole sims available. Corsica makes something very clear. Without water or roads, nobody wants it. Get 100m off a road in the interior of Corsica and you're on abandoned land. Even though people don't seem to drive much in SL, they want roads. Bellesaria got this right.
  12. The viewer collects some performance data and sends it to the server once a minute or so. You can see this in the Firestorm log. What LL does with the data we don't know much about.
  13. Fortnite got 10,000,000 concurrent viewers when they did that. Sansar claims 1,000. Sansar's all-time peak up to that point. What happened around July 25th?
  14. There is a company which makes and sells real boxes of fake products to Hollywood. That's the expensive solution to the problem.

    Coming along nicely. Fall colors, even. Will the trees in Bellesaria all change with the seasons?

    Blender 2.80 advice

    I'm converting files made for SL from Blender 2.79 to Blender 2.80. A few questions. Do you now have to set up rendering nodes and all that just to see what your model with textures? Rendering nodes are useless to SL, of course. If you do have to set up rendering nodes, what's the best match to SL? Will Principled BSDF work and match SL reasonably well? What else has to be changed to make an existing file usable in 2.80?
  17. I think you are way overestimating the value of sex in SL. It's so easy to get for free.
  18. (Duplicate deleted. Server stalled during edit.)
  19. It's not a DMCA issue. DMCA is for copyright. It's more like the "stolen valor" problem. Useful reading on Task & Purpose. You might be able to get LL to do something if you sent them a formal letter on department stationery signed by your chief.
  20. There's Drivers of SL. An event every week. There are many motorcycle clubs in SL. They even have "ride leaders". But I never see those guys on mainland roads. I expected they'd have group runs, like RL bikers, but in over 2000km of SL driving, I've never seen a club run go by.
  21. Oh, you're giving up your place? I liked the Virtual Existence Society HQ. So sad!
  22. SL mainland used to have a uniform 4-hour day/night cycle, with 1 hour of dark and three hours of light. The EEP project messed this up so badly that nobody knows what time it is any more. Whether the sun is out or not depends on so many factors that it's too confusing to explain. With EEP, people don't look at the sky any more because it's so screwed up. Many users just set their viewer to "daylight all the time". It's been like this for most of 2019. ("What SL really needs is more sky options", said no one ever.)
  23. It's not that bad. Sumi's dune buggy fits fine. One of the cars available in the Burns area. It's not hard to get this car across this bridge. (The water area here is mostly privately owned with a narrow and irregular Linden-owned strip for the bridge. Hence the difficult bridge.) A tighter fit. Axtel's Autos is no more; this car was free when he was shutting down last year. This race car is for drifting, not for road trips. It is too hard to control to drive across this bridge without banging into the obstacles.This is what you don't want for driving on Linden roads. It belongs on a track. Yes. Sansara and Zindra have very few Linden-sponsored rez zones on roads.
  24. Those old cars are cute, and free, but very slow. They drive at about avatar running speed. They do have some region crossing issues, but at that speed, the effects are so small you barely notice. I just drove one, the taxi, around Robin Loop, and it took about 3x as long as with a modern car. Easy to drive, but kind of boring.
