[Therion] Need help producing scraps.kml without white blobs

[Michael Ross]

Hello there,

I "own" a fairly large dataset of a maze cave.
Producing PDF output works well,
but when producing kml using

  export map -projection plan      -output Scraps.kml

I get large white blobs where there should be transparency. See attachment.

First assumption was that Therion needs some help by marking certain walls "outline in".
But that didn't help.

Then I tried redrawing the walls of the affected passages to get long lines of walls rather than 
concatenated short sections of walls, assuming that would help Therion to better understand.
Didn't help.

Anyone had this problem so far?

If there is a way to post-process the kml file to remove the white areas, that would also help.

Or any other hint to systematically track this down.

Kind Regards,
Michael
