Exporting to Collada: Physics don't get exported I added basic rigidbody characteristics to a default sphere in Blender and exported it to Collada but the physics information isn't exporting.

How can I get the physics data to be exported along the geometry?

Thanks in advance.

I'm using Blender 2.68.4

EDIT:

As for Blender 2.68.4 there is no support for physics data to COLLADA :(

Althought it seems that there is already a patch to export physics:

http://wiki.blender.org/index.php/Dev:2.5/Source/Architecture/COLLADA

https://projects.blender.org/tracker/index.php?func=detail&amp;aid=25601&amp;group_id=9&amp;atid=127

This patch was already accepted into upstream so maybe in a near version support for this is added :D

I will leave the question open to notify the ones that favorites this question once this functionality is added.

IN THE MEANTIME:

You can solve this issue by:


Saving the scene with physics in Blender format (.blend)
Importing the .blend file into Unity Engine (free edition)
Use the Unity Collada Exporter to get a fully physics functional COLLADA .dae file.

Assuming you want the motion generated by the rigid-body simulation (not the mass and other parameters), you can bake the simulation to keyframes.

There are two ways to do this:

Method one:
In the Tool shelf (N in the 3D view) > Rigid body tools, press Bake to Keyframes:



Method two:
Press 3D view > Header > Object > Animation > Bake action:
