ye olde prim
[Update: You also do this with the Firestorm viewer. Just Export your prim object using the Collada format. Details here on the Firestorm wiki.]
This is pretty cool.
The most recent version of the Singularity viewer (version 1.8.1) adds a particularly interesting feature:
- Wavefront (.obj) and Collada (.dae) Export by Apelsin, Inusaito, and Latif Khalifa – Allows export of your creations into Blender, Unity3D and other modeling applications and game engines
This means you can now take a prim-based object from within Second Life or Opensim and export it to your hard drive as a mesh object (either .obj or .dae file format).
Here’s a short video showing exactly how it works. Watch me create a prim-based lamp in Opensim, export it as an .obj mesh file to my desktop, drag it into the Unity3d editor, and then publish it on the web in ReactionGrid’s multiuser Jibe world.
This is great for folks (like me) who still love to build with ye olde prims yet need to create models that work in mesh-based environments. I can’t wait for the texture mapping feature to be completed (UPDATE: As of today, TEXTURE MAPPING WORKS! You just have to save your object as .DAE. Scroll down for more info.)
Nicely done, Singularity and Opensim developers. Very nicely done.

UPDATE 8/15/2013 @4:45pm EDT:
Latif Khalifa just gave me more details about texture mapping:
I’m working on improving the Collada exporter by adding texture import. I have already implemented it in Radegast which I will use as a prototype for what it will look like in Singularity.
If you want to to check it out, download Radegast nightly build.
Then once logged click on the Objects menu which will bring up a list of objects nearby. Right clicking on an object there will give the option to save as .DAE. You will see the window like this (the left part):
After importing to Unity3D it will look like this (textures and all):
Thank you Latif for this great info and amazing dev work.

UPDATE 9/19/2013:
Texture Exporting now works in the latest release of Singularity!
- Much improved Collada exporter, which now has the ability to export textures, apply texture parameters such as repeats, offset and others to the exported UV map, combine prim faces with the same texture and color into one submesh and optionally skip transparent faces (Latif)
For more details on how texture exporting works, see this very helpful guide.

UPDATE 8/1/2014:
You can now do all this with the Firestorm viewer. Just Export your prim object using the Collada format. Details here on the Firestorm wiki.

Excellent! Thank you, John for sharing this with us!!!
My pleasure.

i successfully exported a 7,153 prim object to .obj and .dae, then imported the .obj into Blender. is there a jibe world where my object could live?
Nice pic! 😉 I’d love to put your object in a Jibe world! If you email me the .obj file I could drop it in the same world as my Lamp. john.e.lester@gmail.com
Done!
Go to http://pathfinder.jibemix.com/jibe/expo_demo.html
When you arrive at the default Expo level, look for the button in the upper left part of the screen that says “E8Polytope” (it will probably take a few seconds to load) and click on it.
Then you’ll see this:

Great find John, thanks for letting us in on the secret!
Wow this is very useful. I wish I known/had it a few months ago before I got rid of my SL sim and build. 😦
I like the rabbit icon!

Very informative, thank you for sharing this 🙂
I wonder whether a reimport to OpenSim brings in the exported textures intct and correctly placed, or if that has to be done manually?
I wonder whether an exported .dae and textures from the Radegast nightly build version can be reimported to an OpenSim world and still have the textures intact without much manual adjustment to fix them?
Much improved version is now available in Singularity Alpha builds from https://files.streamgrid.net/singularity/
Support for texture export, application of texture params to UV maps, skipping transparent faces, merging faces with same texture, etc
That’s fantastic! Thank you Latif!

Do I have to use Jibe? That’s way too expensive for me.
I was wondering, if the collada-files of the objects, once imported in Unity, will be converted into one single mesh-file, so they would be meshs, and not linked prims, when you reexport them to Second Life.
Ok, so at first I thought this was awesome (well, it still is) but then I had a rather frustrating day. I built a gun turret in SL with the intention of bolting it to my ship in Unity for my game. It worked, I got it in there, but after import, every individual prim is there inside unity. I understand why this is, and why it has created multiple materials etc for each texture I used in SL, but the result is, my 10 prim turret equates to 7 draw calls per turret in Unity (some faces shared the same texture). They do at least dynamically batch, but what I’ve been trying to find all day is a reasonable simple workflow for merging these sub-meshes into a single mesh, and simultaneously merging all their texture info into a single material, so I end up with 1 draw call per turret. For the life of me I can’t find out how to do this without having to take a month away from my game to finally learn some 3d modelling! Any tips?

Como exportar de Second Life u OpenSim objetos-prim a objetos-mesh para importar a Blender, Unity, Zbrush, Maya… Se pueden guardar como .obj o .dae
Hey – I’m working with a company that is looking for sites that have content relating to clothing and I came across yours.
Any chance you’d be open to hearing about a way you could link to a merchant and make money in the case someone clicks on the link and purchases something?
Just wanted to see if it’s something you’d be interested in hearing about! If not, I hope you have a great day!
