I had a problem recently in Papervision 3D and 3DS Max using the Open Collada plug-in to export a model.

Everything worked perfectly with the first attempt but after seeing the model in my PV3D environment I wanted to scale some parts of the model in 3ds Max and re-export it. The changes I made in 3ds added a tag in the DAE export file:


1.125775 1.125775 1.125775

I could still load and view the new model in PV3D no problem – but whenever I tried to rotate any part of the collada the object suddenly resized to the scale of my first model. (As if it overrides the tags in the DAE)

To fix this problem I had to Freeze all Object Transformations within 3DS Max before exporting.

Steps:
1. Select the objects you want to freeze transformations fo in 3DS Max
2. Navigate to the utilities tab (Right most tab)
3. Click Reset XForm -> Reset Selected
