The Great Bakes-On-Mesh Debate

Well, we are getting an upgrade to the Server-Side-Avatar-Baking service. That is fact. What the service does is old news. The blogosphere was covering it in 2012. By August 2013 it was considered a success. (Ref)

So, what is the service, aka SSA or SSB? Prior to 2012 the classic avatar skin, tattoos, underwear, shirt, and jacket were composited into a single texture in your viewer and used to render your avatar. This is like the process we use in Photoshop, GIMP, and other image editors when we bake a set of layers into a single JPG or PNG image.

...Wait

…Wait

A significant part of the viewer’s render process was the baking effort. Once I was dressed and my clothes baked into an image safely cached on my computer, I was good. BUT… whenever I saw a new avatar, my viewer had to collect all their textures; skin, tat, bra, and top and bake their clothes into a texture to put on the avatar and render it. Everyone was doing that.

With 6 possible zones (ie., hair, head, upper, lower, eyes, skirt) to bake and 3 of them having 5 layers we were downloading a bunch of textures just for the classic body. So, something like 15 or 20 textures per avatar. In a region with 40 avatars… that is like 40×20=800 textures… if they were 1024 textures that could be as much as 3+GB of texture, admittedly in extreme cases. Plus, our viewer had to composite them before the avatar could be rendered. Each viewer was doing this and the region was coordinating the downloads. Continue reading

From the Server and Scripting UG we hear about more region crossing work. Simon Linden is doing some work on crossings. BUG-214653After half-unsit at failed region crossing on vehicle due to network lag, “Unsit” button will not work.

Crossing regions at speed… fast cars, planes, boats, and motorcycles, have a big problem. I was recently testing an Apolon helicopter. Great fun. But, region crossings are an annoyance. Continue reading

Second Life Content Creators’ Meeting 2018 w10

Getting video of these meetings is a PITA. Medhue (1:27 PM) and I (1:08 PM) both were late getting to the meeting. Medhue’s audio has reverb… which generally comes from room echo… the combination of the sound source (talker) and reflected sound from walls reaching the mic at slightly different times. There are no echoes or room reverb in Second Life™. So, the computer’s speaker output has to be fed back via an open mic or duel channels in the recording app. Neither appears to be the case for Medhue…

I got there a bit earlier. I recorded the meeting, so the source is on my computer. I can edit it and clean up the audio. So, this week I’ll use my video. It takes some time to clean up the video and audio. Plus, Thursday is a busy day for me, RL. So, mine comes out later, like Saturday or Sunday.

The first thing you are likely to notice in the video is Vir Linden’s voice is messed up. In Medhue’s video, Vir Linden’s voice is also messed up but in a different way. So, the problem is in the connections or our computers. I have yet to figure out what’s up with mine.

I’ve cleaned the audio up a bit. But, there is only so much repair work one can do.  Continue reading
