The POVRay extestions to pmask by Hans Mikelson have not been already
ported to OMDE/pmask (but it is not that work).
I think that with the new syntax of pmask.cloud() and pmask.sequence() and
with the use of generic contructors (other that I for Csound i
statements), Hans should be more free.

I definitely have to learn POVRay!

I have never used POVRay with or without pmask.
If I understand correctly you used the "time" field to index of different
object in the scene as if each object was an "event". Now you are
proposing to use event as frames.

I'm not able to see the problem as I have no direct experience. I can only
point that you should have less problems since in OMDE/pmask in are not
create ScoreSection using a cmask-like generation model. In OMDE/pmask
there are Aggregate (omde.score.Aggregate) that can be filled using one of
many algorithms. If you want to generate a cmask like cloud, instead of
using something like

section = ScoreSection(start, end, instrument, ...list of generators...)

you create a Aggregate using the pmask.cloud or pmask.generic_cloud
algorithms

a = cloud(start, end, instrument, ... list of generators ...)

but you can also use pmask.sequence (variation of cloud) or your own
algorithm using pmask generators or something else.

You should have more freedom to include POVRay specific algorithms.
