About the VolumeRendering module,
when I select GPU as render, no image can appear in 3D view,
but when I select CPU rendering, it can appear,
but when I change other computer, the result is the opposite.
CPU rendering should work anywhere, unless maybe you run out of memory of something - you can check for error messages.
GPU rendering may not work on some graphics cards due to hardware or driver limitations. These may or may not result in error messages.
