Hi Julian
I'm not sure whether this should work or not. Topo ops are not fully
supported:

eometry
The fact that the op is getting the original geometry at each update
rings a bell, but I cannot remember where I've seen this before.
I tried with a self-installing op, and I set the Topo classification on
an op parameter, but it made no diff.

Subject: [scripting] Problems with Geometry.Get2/GetGeometry 2 in
Runtime SCOP
I've written a test runtime SCOP (for a geometry script I'm writing)
that should simply add another quad to a mesh on each frame (displaced
on Z by 1 unit). Essentially, at the beginning of the Update function it
reads in the existing Geometry using Geometry.Get2, adds a poly to that
geometry and then writes it back using Geometry.Set.
Geometry.Set successfully updates the geometry but when the next update
is called, Geometry.Get2 does not get the updated Geometry description.
Instead, it looks like the SCOP is picking up the geometry description
from frame 0 but not subsequent frames (where it's been altered). Anyone
have any ideas? In the SDK it talks about using GetGeometry2(frame) but
this isn't allowed in the context of an operator. I *think* that within
the context of a SCOP Geometry.Get2 should automatically pick up the
geometry on the current frame...
The SCOP is attached:
scop_getgeo.py
Bizarrely, if, instead of calling Geometry on each frame, I just cache
my own geometry description into UserData, the SCOP works fine. See:
scop_userdata.py.
Is it possible, within the context of a SCOP, to call the updated
Geometry on each frame using Geometry.Get2? Should it be possible?
