After 22 years... why do textures take so long to rez?
"If the 2D don't work, the 3D don't work". I was at Sci Fi Con 17. All day long, no matter how many or how few avatars were on a region, textures took ruddy ages to load. Now one might say "There are so many textures at a big event it just takes a long time." But I'd walk into an enclosed room... where textures should be limited, yet the vendors on the wall just sat there and sat there and sat there. Textures RIGHT NEXT TO ME fail to load. One can stand there and stand there and stand there... and they still don't rez. I would click on a texture and tell it TEXTURE REFRESH... and it would ignore that instruction. I first reported texture issues and bottlenecks back in 2005. Now my computer and graphics card is hundreds of times more powerful... and textures still load at a snail pace. I will say the same thing I said back then: There is a texture bottleneck on SL. (Or, several texture bottlenecks, and it affects EVERYTHING.) With respect, I'm not asking for an explanation, nor excuses. I'm making a simple observation: After 22+ years online, Second Life should be able to very quickly load 2D textures in an enclosed room. Is this not correct? I suspect there will be people all too ready to give reasons why textures load slowly. To any and all such reasoning, I have one answer: Second Life needs to make textures load quickly. There's no argument, debate, discussion or excuse to that simple statement. Users need textures to load quickly enough that we don't get bored standing in a store (waiting for vendor textures to load)... and decide to go do something else. Like Netflix. ;D Because that's what it is: Second Life vs Netflix. Users have options on how to spend their time. When Netflix can stream entire videos realtime, surely Linden Lab should be able to send 2D textures across the Internet... yes? As a note: I'm not going to debate nor discuss or argue with those who are always ready to argue on these feedbacks. The feedback is posted, I've said what I came to say... and I have to believe the vast majority of SL users will agree with this: textures on SL need to load faster.

Highlight Transparent still broken, now HUD Attachment highlight is missing
As you can see in my last comment added here on 30 March 2026 which was ignored ever since: https://feedback.secondlife.com/bug-reports/p/alpha-mask-highlight-vanishes-under-alpha-blend-highlight-when-highlighting-tran After the "fix" for the previous issue by RyeMutt in the SL Viewer 2026.02 preview, as well as in a Firestorm preview that has already imported the supposed fix. The alpha mask highlight issue is gone now indeed, but the other aspects got much worse: 1: Transparency highlight from HUD attachments is completely missing. 2: The transparency highlights got even much brighter than before. Screenshots: Firestorm 7.2.3.80036 (same behavior as in SL Viewer 2026.01), dark: https://prnt.sc/nXv-RBS9g8NK Notice how bright the red highlight on the trees inworld is compared to the red highlight on the HUD. It is very similar to the difference "fullbright" makes on textures inworld. All highlights used to be as dark as on the HUD in this picture before V7. Firestorm 7.2.3.80036 (same behavior as in SL Viewer 2026.01), daylight: https://prnt.sc/TpXjUSOph4il Notice how bright the red highlight on the trees inworld is compared to the red highlight on the HUD. It is very similar to the difference "fullbright" makes on textures inworld. All highlights used to be as dark as on the HUD in this picture before V7. Firestorm Nightly Preview 7.2.4.80397 (same behavior as in SL Viewer Preview 2026.02), dark: https://prnt.sc/DiNdfzWFrn6X Notice that the HUD has no alpha highlight at all. Alpha mask blue highlights show through now as intended but the entire highlight overlay got even brighter, a lot. SL Viewer Preview 2026.02, daylight: https://prnt.sc/dPFeb5oWR3ck Notice that the HUD has no alpha highlight at all. Alpha mask blue highlights show through now as intended but the entire highlight overlay got even brighter, a lot. This can be a showstopper for creators who make HUDs or adjust HUDs for their products, I think I'm not the only one who first assembles the HUD links rezzed inworld, then adjusts the parts while wearing it on the HUD. Editing parts with transparency will be nearly impossible with the highlights missing. The other problem is this excessive brightness on the highlights. If most people were fine with how bright it already was, and only some of us got headaches from this, now this is at least 4 times brighter and it is going to burn out more people's eyes while trying to work with transparent objects. This is apparently because the alpha debug overlay is included in the HDR exposure pipeline which increases the brightness of these textures, it also makes the red and blue alpha highlight visible on reflections on objects when "highlight transparent" is enabled. This shouldn't happen, the highlight shouldn't be included in reflections and it should be rendered separately so that it wouldn't be affected by lighting and it wouldn't affect reflections. Now that the missing transparency highlight on HUD attachments will be in the next Firestorm release, creators and anyone else who edit HUDs and need to see their transparent parts will have to revert to 80036. While there was a workaround for the vanishing alpha mask highlight, there is apparently no workaround for the missing HUD attachment highlight.

Camera sporadically jerky on vehicles
I spent days trying to find the bug in my flight physics code that was causing this, only to discover that it was the viewer camera all along. The problem is that sometimes the aircraft flies "visually" smoothly at any speed up to 100 meters/sec; and other times it's visibly jerky, appearing to "vibrate" (change in apparent size many times/sec) as though the camera was acting like a spring instead of being fixed in place behind the vehicle. I'm using the eye/offset calls: llSetCameraEyeOffset(eye); llSetCameraAtOffset(offset); This is because the "newer" (21 years old instead of 23) follow cam is missing features that would be necessary to produce the same behavior, and I find it unsatisfying and confusing to use for aircraft. I instrumented my vehicle with code that captures llGetVel() and llGetOmega() 20 times/sec (rotated into the local reference frame), then uses llSetText() to display mean, standard deviation, and range once per second. What I discovered: Sigma (standard deviation) for local X can be very low (0.0 to 0.02) in level, unaccelerated flight regardless of whether the visual apperance is jerky or not. There is no difference. When it's visually smooth, sigma can actually be quite a lot higher, closer to 1, and it still looks totally smooth. This happens during accelerating and turning. Local Y's sigma is typically very close to 0 in either case. Local Z's sigma is typically very close to 0 in either case. All three axes of llGetOmega() are always zero unless the aircraft is turning, climbing, descending, or yawing. If the statistical analysis is not enough of a smoking gun, here's another: When the aircraft is flying smooth, and I refocus the camera on my avatar, it starts getting jerky, like the camera is damping at some wild speed. Single-frame jumps of tens to hundreds of pixels along the axis of motion. The attached screenshot is the llSetText() stats output when the camera was jerky. Zero standard deviation in this regime + jerky visuals, vs. standard deviation WAY higher during maneuvers when the camera is smooth, provides strong evidence that this is a viewer bug. My code is invariant either way. My stats are invariant either way. When flying smoothly, refocusing the camera makes it do the jerky rendering thing. And sometimes it does the jerky rendering thing whether I do that or not.
