Hello everyone, I’m working with a CT volume dataset and experimenting with the volume-rendering presets. I’d like to apply various changes to multiple presets and save all of them. However, when I save the scene using the MRB file format, only the most recent changes to the last preset I used are saved.

Is there a way to save all the modifications I’ve made to the different presets?

Thanks in advance,

You will probably need to save them as new volume property files for changes to be retained.

Okay. But I’m wondering whether it’s possible to upload them separately while keeping the same scene, without having to reload the entire scene using a different volume-property file?

You mean modify the preset with your own customization and make it persist between Slicer sessions? That’s currently not possible. There has been some discussion about adding a functionality about creating and adding custom user presets, but I believe it is not ready yet.
