[Therion] How to render very big cave with centerline and LROU only?

[Benedikt Hallinger]

Hello,
this did not work unfortunately.
However i got a solution.

The data structure looks as following:
MyCave
+---Region-A
|   + Survey-1
|   + Survey-2
|   - ...
+---Region-B
|   + Subregion-B1
|     + Survey-B1-1
|     - Survey-B1-2
|   + Survey-2
|   - ...
...


The error occurs with the map defined in compilerfile as:
source
   map onlyCenterline -projection plan
       MyCave
   endmap
endsource


It does NOT occur if i specifiy every sublevel explicitely
source
   map onlyCenterline -projection plan
       #MyCave
       Region-A at MyCave
       Region-B at MyCave
   endmap
endsource


This seems to be a usable workaround. It would be interesting what causes 
the error, tough.


Greetings,
Beni
