problem with .dae mesh in quartz composer

[mowgli]

I have a quartz patch which imports a .dae mesh using the mesh importer and is rendered using the mesh renderer. It all worked fine on my macbook pro running osx 10.6.8 but when I moved the files to a mac pro running lion my mesh doesn't display. The mesh was created with blender and has a uv texture.

Any clues?

thanks

I've re-exported the mesh from blender without the uv and it does appear in quartz, any suggestions on how to resolve it?

Hi Mowgli, have/had the same problems with .dae files on lion 10.7.4. I tested them also with vades v002 Model Importer, but the textures were not loaded.
My Quartz Composer Files were produced on Snow Leopard 10.6.8 and rendered the .dae Meshes with the mesh renderer without problems.

Here my quick and dirty solution that works for me: open the .dae file with Photoshop extended (CS5 - 6) and export the Mesh from there.

Here the Quartz Composer Error Logfile (.dae file from blender 2.63a and mesh renderer):
