Single block image volume rendering
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If you have a multiblock data set with a single unstructured grid, you can volume rendered it as if you just had an unstructured grid. You cannot do the same thing with image data.
If you have a multiblock data set with a single 3D image data, you cannot volume render it. You should be able to. Please add this feature.
