Hi to everyone 🙂

In this case I’m struggling with transformations and Segmentations. The problem is the following one:

-I’m trying to apply by code a linear transformation to a specific segment contained in a segmentation with more than one segment.

As far as I know, transforms module only allows apply transformations to segmentation nodes.

Can I transform only one segment?

Thanks a lot.

No, you would need to move it to a new segmentation, apply the transform, and then move it back.
