Ok, makes sense.
then I believe it could be a split problem.
sometimes, in rare cases it can be that if no follow-up shapes are well-enough defined in the split, the split will fall back to the incoming shape.
use the model hierarchy and edit model mode to track down precisely in which part of the code these white polygons are produced. if it is a split, then have a close look on why these polygon duplicates are created.
to explain the behavior that I mean:
--------------------------------------------------
If you use scatter() with 0 points, no resulting geometry can be placed. But unless you explicitly say ..
scatter() ... 0, ..
NIL
.. CGA will fall back to the shape that comes into the scatter() operation and falls back to that one instead of continuing with a non-valid geometry ( after scattering 0 points).
Adding a NIL in a specific location COULD solve this issue.
Ok?
