I am wondering if we can direct our cpu allocation to favor ScenPro processing
.Using the SplitGrid command already allows scenProc to process the multiple grids simultaneously. This is already enabled in my template. I also noticed a low CPU and memory usage with scenProc even when it is working hard, unlike GeoConvert. This is probably something you should ask Arno the creator of scenProc.
I am missing most of the residential houses in the cultivation here.
The lines you have indicated are only for large residential buildings, which usually means residential high rise. Further up your screen shot I see that you have created 2364 single level houses and 918 double level houses. So it seems to be working as expected.
