<p>Ahh!  Mesa.. of course! (I’d completely forgotten about that project)</p>
<p> </p>
<p>All I had to do was install Mesa on the VMs and that has enabled them to use software rendering without changing a line of code.</p>
<p><a href="https://github.com/pal1000/mesa-dist-win">https://github.com/pal1000/mesa-dist-win</a> was really helpful here and just did a system wide deployment for my test VM.</p>
<p>This enables us to at least deploy this on our automated test environment and get things going there.</p>
<p> </p>
<p>I’m using VTK 8.1.0 atm, but will look at the helper when I upgrade things and try and do this better.</p>
<p> </p>
<p>Thanks David!</p>

<p>In VTK 8.1.1 on windows, there is a helper that:</p>
