@lassoan I am not able to reproduce following the following steps:

• Create Segmentation using Paint effect and show in 3D
• Add segmentation under linear transform 1, update transform 1
• Export segmentation to model
• Add model under a new transform 2
• update Segmentation
• re-export segmentation

=> model is exported under the transform 1 (the one associated with the segmentation)
=> newly exported model is not related with transform 2 anymore

Is this is the expected behavior ?

I tested and I found the same as Jc. After exporting the segmentation to the same model hierarchy (in which the model was under a different transform than the segmentation), the model's parent transform was set to the same as the segmentation's.

Thanks for testing this. The problem happens only when Segmentation is in the root (no transformation is applied) and the target Model node is under a transform. In that case the Model node's transform is not removed. I'll commit a fix shortly.

Makes sense. Probably the SetAndObserveParentTransformNode was inside an "if (segmentationNode->GetParentTransformNode() != NULL)", and it was not propagated when the segmentation was in the root.

That was exactly the problem.

Fixed in r26423

Great, thanks!
