No, that doesn't help. I think I found the problem, but I don"t understand it. Thomllama, I think we had the same problem and the obj did the trick.

This is what is happening. If I create an object in Carrara, a Transform section is created on the Motion tab. But if I import a dae file, some weird things are happening. Besides the Transform section there are also a Translation, Rotation and Scale section created above the normal Transform section with strange and very high values. Whatever I do with the imported object, the 3 weird sections do not respond. The Transform section acts normal. If I export and import as obj, the 3 weird sections are gone and I have only the regular Transform section.
