B.1 SYMBOLOGY: For aesthetic purposes, terrain symbology may extend marginally out of a hex into an adjacent hex of another type, but most hexes are dominated by one specific terrain type and are governed by the rules for that specific terrain type
Hm, seems unlikely, because R3 and some adjacent hexes don't have Dense Jungle, so it is probably not a Terrain Transformation in VASL. Looking at the Map/Terrain, it is probably not an Overlay either - AFAIK, there are no specific 'Dense Jungle' Overlays but merely Woods overlays.What board is that? I assume it's a DenseJungle overlay, but why wouldn't R3 and other hexes have DJ?
There's a generic "X to Y" transformation that can do Grain to Woods, and that's what the original post pic looks like. If it were a scenario special overlay, one would think it would have transformed the Grain into Dense Jungle as per the SSR, and of course changed the hex IDs to white. Unless of course those are some cheap off-market SSOsAm I missing something?
OR4 is a totally Open Ground hex. No TEM.
