I get the above error which I am suspecting is related to the scan numbers in this ms which are [2, 36, 6, 40, 10, 44, 14, 48, 19, 23, 27, 31]
Here is the branch I used: https://github.com/IanHeywood/shadeMS/tree/harlequin

Yep, you're right, there was a sort operation missing.

Could you please try the fourth-wall branch now?

I am getting a different error now

Ah. Install the master version of dstashader from github. I'll take out that dependence tomorrow. Cheers, Oleg

It is running now. I have screened it. I will check the result in the morning.
