Operating system: Windows 10
Slicer version: 4.8.1
Expected behavior: I am following the CT Thorax Abdomen tutorial to have a first look at volume rendering. The expected behavior is described in the tutorial.
Actual behavior: When I click on the eye-icon in the Volume Rendering module, all I see is that the bounding box changes color to white, and a coordinate system appears. There is no rendering of the data. I tried using CPU or GPU rendering, nothing changed. I also made sure in the NVIDIA driver settings that Slicer is using the GPU and not the integrated chip. I am using a Dell Precision mobile workstation with a Quadro M1200 GPU.
