Hi Max, The downsampling of images draped on meshes during export is a function of the type of terrain mesh being used and whether or not you are using V8i or Connect. Let's say I had aerial imagery consisting of 8 images I draped onto the terrain: 1). For standard Terrain Models (TM) found in basic MS and things like InRoads, even if you used multiple 8k x 8k images draped on the terrain, the output to LumenRT would be downsampled to s ingle 1k x 1k (V8i) or a single 4k x 4k image (MS Connect) 2). For Descartes Scaleable Terrain Models (STM), the 8 draped images would be turned into mesh tiles depending on how close or far away from the camera the STM is. At a medium range distance, you would get something like 8 tiles each having 512 x 512 resolution, so this would be higher effective resolution than regular Terrain Model (TM) output. 3). The highest possible resolution would be the new Reality Meshes. These basically output 512 x 512 or 1024 x 1024 images for all the tiles with each mesh tile being quite small. Also, in LumenRT Update 2 (later this month) you will be able to use the scaleable reality meshes meaning that there is no fixed resolution -- it will use all of the input maps resolution depending on how close the camera is to the mesh.
