		<description><![CDATA[OK, not everyone in the immersive modeling universe has been holding their breath on this one, but hey, I&#8217;m happy to say that the production line is fired up and creating 2560 sculptie bumpmaps to inflate the Open Berkurodam sim using LiDAR reflective digital elevation model (DEM). The registration with orthoimagery is not perfect, and [...]]]></description>

		<description><![CDATA[There has been a bit of head scratching as other distractions apparently clouded an obvious scale issue. The first terrain megaprim sculptie project done last month, had available imagery at 30cm.  For that, it only made sense to oversample to 25cm to make 512&#215;512 textures.  That decision led to my adding a collar around the [...]]]></description>
