Do you want to “color” (it will be all just different shade of gray) the models using the CT values? You can do that with [Probe Volume with Model module](https://discourse.slicer.org/t/mapping-intensity-values-to-model-surface-as-texture/6972).

Usually it does not result in very interesting or nice-looking images (especially if you segment soft tissues in CT). See some discussion in these topics:

- [Mapping intensity values to Model Surface as texture?](https://discourse.slicer.org/t/mapping-intensity-values-to-model-surface-as-texture/6972)
- [Retain Image Color in Volume Rendering](https://discourse.slicer.org/t/retain-image-color-in-volume-rendering/12294)
