Static Models
Static (boneless, unanimated) models can be transferred from blender using either DAE or one of the more popular still mesh formats like obj or 3ds, transforming them into DAE by using the autodesk converter or a similar tool. Info on this process can be found here, Autodesk FBX converter to ShiVa
Blender 2.6+ Workflow
This tutorial covers how to export a static model from Blender with all lighting baked into the diffuse map, which is ideal for mobile devices.
Do not forget to assign a UV map to your model/material.
If you are working with more than 1 layers in blender, select the object you want to export and include only this UV layer:
When importing into ShiVa, swap Z and Y axis:
Edit the material inside ShiVa to give your models the final look, and there you have it!

Animated Models
Parenting to a Root Bone
Both the armature and the model need to be located at (0, 0, 0) and the scale needs to be (1, 1, 1). The key point that I've been missing is the bone that is between the feet in the attached picture of the robot. Any bones that don't have a parent (in this situation, the spine and hip bones) need to parented to this "root" bone, which must also be positioned at (0, 0, 0). Doing this seems to force the parent-less bones to stay in place when the file is imported.
Animation
It is very important that the model and armature need to be exactly in same pose at the start.
Take 60 fps as an animation speed guideline, as it is shiva's default setting. If your blender animation speed is different, your model will require additional coding to make it look right.

2.5x notes
- Pose your mesh and armature at x:0, y:0, z:0, also mesh and armature rotation also must be 0,0,0
- Be sure your armature is in rest position when exporting
- You must have a root bone (name it "root") on 0,0,0 too, the base of it; parent that bone to the spine.
You will have to apply size/rotation to mesh/armature to achieve this. But rotating armature could lead to animation deformation; so it is better, if you need differend orientation of a model, to apply rotation in ShiVa dae importer.
