<p style="margin:0px 0px 1.2em!important">I don’t believe there is a technical limitation. It was merely that the original effort for adding multiple overlapping volumes support was focused on selected features. I am not aware of current efforts/funding to add support for additional features like shading, different blend modes, etc.</p>

<p class="MsoNormal">Hello,<u></u><u></u></p>

<p class="MsoNormal">I’m experimenting with using vtkMultiVolume to add proper multi-volume rendering support into 3D Slicer. My main question is the reason behind this actor not supporting shading, as apparent when used, but also mentioned in the corresponding
 test:<u></u><u></u></p>
<p class="MsoNormal"><a href="https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastMultiVolumeOverlapping.cxx#L229" target="_blank">https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastMultiVolumeOverlapping.cxx#L229</a><u></u><u></u></p>
<p class="MsoNormal">Is this a technical limitation that would be very hard to overcome, or is it something simpler? I’m asking this because for this actor to be really used for volume rendering, shading would be necessary.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thank you,<u></u><u></u></p>
