What causes these bokeh artifacts and how do I cure them? Should this be RFE'd? Jan. 19, 2018, 8:12 a.m.

Nope - my bad. Pixel Samples does cure it, though you need to whack it right up (32x32 seems good):

Request: Guide to setting up a simple render farm for us Indie users Jan. 19, 2018, 7:01 a.m.

I've got multiple machines - Macs and PCs - but I've struggled to understand the hQueue docs, and a step-by-step guide for one-man-bands and small studios would be ace.

This was very simple with other 3D packages (just load the same scene on all machines, point them all at the same output folder, have them all skip existing frames, set them all going) but Mantra only seems to check for existing frames when you hit Go, and not after each frame is complete, so the machines all end up rendering the same frames as each other.

Rendered with just depth of field enabled:



Rendered with just motion blur:



But with both, everything goes splotchy:



Doesn't seem to be related to Pixel Samples, or Geo Time Samples. How do I cure it?
