Blender Update 2.59 RC

There is a new Blender release out that several people are using with Second Life. Results are varied in regard to rigged mesh.

The current ‘stable’ release is 2.58a. If you search on Blender Download, you will find the 2.58a download files. The 2.59RC is hidden away in the development sections. Download Blender 2.59RC. If you move up one directory/folder you can see all the Blender releases. All the version information shows the version as 2.58.1. But, the archive is clear this is the 2.59RC.

Blender 2.59 Release Candidate - Uses older art

The download I have linked to is the ARCHIVE not the Installer. If you are not using the Blender Archive for your install, you’re working too hard to get Blender installed. See my article Blender 2.57b Released for information on how to do easy installs and upgrades.

I’ve added a Blender page to my blog. Blender news, tips and tutorials. You can find the link in the menu under that geeky technical term: The Stuff.

A ‘release candidate’ is not a stable version. Often there are parts of the program that do not work as expected or planned. But, there is a single feature in this release that I find highly valuable. Rage Riptide, an SL resident, pointed out in the SL Forum that the Collada export now has a feature to export only the selected objects. That is a big plus for me.

The problem with Blender and its Collada export is with rigged mesh. Blender 2.49b exports a usable rigged mesh in the sense that will import to Second Life. Newer versions have a problem. Rigged mesh made with the newer versions fails to import. Other mesh works ok. The Lindens will probably not concentrate on fixing the rigged mesh problem until sometime after initial mesh roll out is complete.

There is some confusion over what has or has not been fixed in the SL Mesh Capable Viewers. The 2.8 and 3.0 versions will import Blender objects. The JIRA items CTS-660, CTS-757, and SH-1853 are about the problem of Collada version 1.4.0 and 1.4.1 support by the Lab in regard to rigged mesh. Be sure to Vote and WATCH those JIRA issues if you are working with rigged mesh.

I have heard the difference between Collada 1.4.0 and 1.4.1 is very small. Supposedly supporting either version should work.  So, which version SL supports is not the issue as much as how well they support Collada.

I don’t see much difference between 2.58 and 2.59. The Blender 2.59 change log is here. Most of the changes do not affect what I do.

One addition is: New option for multires modifier: Subdivide UVs – r38783

Another interesting addition is: UV Straighten tool – r38598

Another: Object Align: high quality option for perfect alighment – r38511

A fix I think may affect me is: fix #28079 UV proportional editing was incorrectly influenced by the mesh X mirror option – r38699

I have not run into this but I’m glad it is fixed: fix #27819 Unwrap Menu (U) -> Lightmap Pack throws Python Exception – r38212

In regard to Collada: fix #27854 Collada import doesn’t handle UVW mapping – r38169

And what I think is the big improvement: option to export only the selection – r38079


Blender is probably the modeling tool most hobbyists in SL will use. So, I expect the Lab to get it working with rigged mesh. I understand if it is a Collada or Blender issue we will have to wait for those groups to make their fixes. We will also likely have to wait for the initial roll out of mesh to complete before we see any extensive progress on this issue from the Lab. But, eventually it will get fixed.

  1. I had to rollback to Blender 4.9 and Python 2.6 in order to be able to do any animations that I could upload to SL. I hope this gets fixed soon as I really liked working with the newest version of Blender but was very disappointed when I found all my hard work would not upload successfully into SL.

    • Several of us work in 2.5x and then open the file in 2.49 to do exports. We DO NOT save while in 2.49 as that can break the file for 2.5x.

  2. The final version of 2.59 is out now 🙂

  3. Supposedly there is a fix but tried it and still had same issues…

    What I get when I try to export with the fix in 2.5 is a bvh file that is 0kb.

    I assume what you are saying is you do the blend file in 2.5 and then export via 2.49?
