Removing 3D model to view segmentation

Hello all. I had some questions regarding segmentation. I have recently finished segmenting a 3D soft tissue model. The issue I am having is the grey 3D model I had segmented still remains in the image. I have attached a screenshot (

) I have segmented the grey part but have removed it to show the original grey model that I would like to remove. Is there any way to remove it temporarily to just see the segmented tissues? Thanks!

The gray object seems to be volume rendering of the image. If you use a recent Slicer Preview Release then you can toggle visibility in data module by right-clicking on the visibility column:
