More textures, OpenSim 0.5.4_4272 OK after Hardy Heron 8.04 update

Published by under SL In General

The manual process I’ve been using to place the terrain megaprims is crying out for automation, but for the moment, I’ve added it only incrementally. I have three OpenSim command scripts now for the three scales of terrain megaprims, and these use edit-scale to supersize the seed prims that I am still putting, four to a reigon, in starter positions by hand.

I’ve had some trouble with my SL client not always showing me all items in inventory. Also, I fixed the one problem terrain megaprim. Apparently it was a naming convention error from when I created the three sets of different-scale terrains as 8-bit, and the problem prim was where I first realized that ERDAS Imagine dicing was starting the tile names anew for each of the rescales, and this was confusing as all three had different upper-left origins.

Even so, I’m only up to having 19 reigons populated with surface terrain sculpties. It is rather satisfying when the megaprims get sized as cubes, positioned appropriately in 3-space, then converted to giant generic sculpties—and when the proper terrain UV is applied, they just snap to the terrain like a fairly decent coat of paint the instant that I select the next prim.

The imagery is tiling very well and that is also satisfying, when I turn on Full Bright and see good detail. It seems that the key to perfect tiling is to adjust the leftmost texture tiles to have a -0.064 horzontal shift to their 1.000 scale texture, and the topmost texture tiles have an 0.064 vertical shift. The upper-leftmost tile has both. I even found a farm in Berkeley–go figure. Looks like they were growing strawberries near Oxford and Hearst on 1 July 2006.

Not to be deterred by having everything going well, however slowly, I opted to test the new distribution of Ubuntu tonight. My “save-xml” scripts ran without warning, but following the OS upgrade, and verification of graphics and browser, my load-xml script only place about one good megaprrim per region. I’ll dup them and get back on track soon. The browser (Swiftweasel) had nary a hiccup, and still runs Flash just fine. My Nvidia display driver kept on working, and I did not need to re-install it as I had been warned when first installing the driver by Envy. The default desktop has a cool Heron on it, the System Monitor has transcended its previous Windows-like aesthetic and improved the dashboard. MySQL seems to be unaffected by the upgrade. Eclipse Europa launches in about 15 seconds. Things feel just a bit faster in many departments, including the rate at which OpenSim draws land.

What’s next:
1) I’d like to finish my way through building the 40-region model on the local OpenSim server here in the lab
2) I’d like to craft a 1:25 scale model of the entire 160-sculptie terrain on Agni in a parcel on Amida not far from to the Berkurodam BART Station 1:3 model.
3) if Hardy Heron holds together for the next few days of testing, I’d like to build a public-facing version of the OpenBerkurodam model, at least as a standalone sim

.Possible build site for 1:25 version of OpenBerkurodam on Agni
