5. Decomposing mesh for physics shape

Mesh models must be created outside Second Life using a third-party 3D modeling tool. If you're a seasoned content creator, you may already be familiar with 3D Studio, Maya, Blender, or other popular professional tools; Google's SketchUp also provides a low barrier to entry for aspiring 3D modelers. Any 3D modeling software will work, as long as it can output models in COLLADA (.dae) format.

A list of software that has COLLADA support can be found at COLLADA.org Products Directory A very extensive list of 3d software can be found at 3Dlinks.com under the software section. Which of either the COLLADA or 3Dlinks items will work with Second Life is not known, but at least it is a starting point to look.

To learn more about some of the available 3D modeling tools, visit the 3D software guide created for use with sculpted prims. Most of the tools that work for sculpted prims should work with mesh, as long as they can export models in COLLADA format.

Collada(DAE) Supported Programs for Mesh

Notes on mesh support for specific versions of various applications - please update if you have additional information:

Programs	Bone	Method	Version
3Ds Max Studio	Yes	Import/Export via OpenCOLLADA Plug-in	2009 or higher, No support for bones or UV mapping
Bentley's MicroStation	No	Import/Export	V8i and up
Blender	Yes	Import/Export	2.49 and up
DAZ 3D	Yes	Import/Export	2.0 and up
Lightwave	Yes	Import/Export	9.5 and up
Maya	?	Import/Export via OpenCOLLADA Plug-in	2008 or higher, No support for bones or UV mapping
Modo	?	Import/Export	?
PhotoShop	No	Direct open	Creative Suite 4 (11) and up
SketchUp	No	Import/Export	5.0 & 7.0 and up (6.0 was not supported)
Wings3D	No	Import/Export	1.2 and up

General Tips

• For the best results, first try outputting individual models before trying whole 3D scenes.
• If you already have a library of 3D models and need a way to convert them to COLLADA format, try Autodesk's FBX Converter (our preferred converter) or MeshLab.

Note: If you use FBX converter, you may need to convert your models to an intermediate format, then to DAE, depending on the original format.

Specific Software Tips

Autodesk 3ds Max

Tests of moderate complexity models worked with the following conditions:

- 3ds Max 2010 with Connection Extension and OpenCOLLADA plugin.

- Object was Editable Poly, with other items removed (dummy objects, lights, rigging, etc)

- Units was Metric cm
