COLLADA2POD v2.08 not exporting mesh

Hello everyone,





I made a 3d model with an armature (but no animations) using Blender 2.57a. I then opened it in Blender 2.57b to export it as a COLLADA 1.4.1 file. The file is available at the following URL:





http://www.machcubed.com/penguin.dae





I then downloaded the latest SDK today, version 2.8, and used COLLADA2POD with the following settings:





Export geometry: on


Export matrices: off


Fixed point: off





Export materials: on


Merge: off


Invert transparency: on





Export animation: off (there’s no animation data anyway, just an armature)





Coordinate System: OpenGL, World space


Static frame: 0





Normals: on


Vertex colours: off


Mapping channels: on


Flip V coordinate: on


Generate tangent-space: off


Interleave vectors: on


Align vertex data to 32-bit: on


Export skin modifiers: on


Matrix palette size: 9


Primitive Type: Triangle list, Indexed


Triangle Sort: PVRTGeometrySort, Sort vertices


Vertex vector formats: default





Post-export command line arguments: none





Output:

When the exported POD file is opened in PVRShaman, the light, camera, and material are all present, but not the mesh or armature. What's going on?



Note: I tried to install PVRGeoPOD in Blender 2.57, using, but the option to export a POD file directly from Blender 2.57 isn't visible in File->Export. I tried again after changing the line Blender: 249 to Blender: 257, but that didn't help at all. Is PVRGeoPOD incompatible with Blender 2.57 ATM?



UPDATE: My COLLADA 1.4.1 file won't open in Preview, nor will Blender import it successfully. How do I do a COLLADA 1.4.0 export from Blender 2.57?MachCUBED2011-05-25 21:53:11

Sorry for the delay. We’ve taken a look at your Collada file and it doesn’t appear to be complete as it has an empty controller library and nothing references the mesh data. This would explain why the mesh isn’t exported to POD from Collada2POD.

I wonder how it could end up with an empty controller library and all. Could it be an error in my .blend file?
