you can try setting the wrap property to pinned.

For BSpline and Catmull Rom curves, this wrapping option tells the renderer to add “phantom points” to the curve which cause the visual representation of the curve to start exactly at the first vertex position, and end at the last vertex position. The renderer is expected to compute these phantom point positions automatically.

yes thats exactly what we are doing. running them over the farm with the task size limit of 1.
just wanted to make sure theres nothing we can do to lift that limit if we wanted to. Thanks a lot for the explanation.

hi, thanks.

tried:

frame = hou.frame()
prim = stage.GetPrimAtPath("/Render/rendersettings")
attr = prim.GetAttribute("dataWindowNDC")
attr.Set((0.1,0.7,0.6,0.8), frame)

but getting the same results, working with prerender and not with preframe argument
