[John Richardson]

Works under 10.11.5 and 10.11.6.

Note: High end Radeon with 4GB of graphics RAM.

Dave

Thanks for the detailed reply. It may be that the problem with X3DOM volume rendering under El Capitan is the combination of the new Metal framework and the GPU on my older Mac Mini (the graphics is Intel Iris, politely described as 'low end').

Time to visit the Apple Store and check this on a variety of Mac models.
