<div dir="ltr">Also, to add to that, osgdem relies heavily on GDAL to ingest raster data. GDAL has several tricks for combining multiple files or directories and referencing them as one dataset.

<br>
It's probably getting on decade since I last used or did any serious<br>
worked on VPB so can't recall the specific command line options to use<br>
off the top of my head. So will just provide some general notes that<br>
may help.<br>
<br>
It's possible to have osgdem (single process build) and vpbmaster<br>
(multi-process distributed build) using a directory as input rather<br>
than individual files. Run osgdem -h to get the command line options.<br>
You can generate a single source file from your initial input<br>
parameters and reuse that source file subsequently - this is what is<br>
also used in the distributed build.<br>
<br>
I'm afraid I can't help beyond this without sitting down at my<br>
workstation to do some test builds after doing re-learning of the<br>
command line options.<br>
<br>
FYI, in the coming months I'll be doing some work on paging in for the<br>
VulkanSceneGraph project and will likely do some work with VPB to get<br>
it to generate native .vsgb rather than .osgb files. At this point<br>
I'll need to dive back into VPB and re-lean how to use it properly :-)<br>
