The alien has arrived & its hungry. Prepare to be infested!
5th edition 40K brings strict line of sight to the terrain rules. The solution is area terrain with defined places for all objects. A 1/4 MDF board is drilled with sockets for 60mm and 40mm wooden disks. Look for this terrain system at the upcoming Adepticon convention.
For these two terrain sets, each disk holds a mini-diorama built from Hirst Arts blocks, PVC pipe, a plastic Easter egg and lots of Terrain Putty (light tan) & Apoxie Sculpt (light gray) epoxy putty. In addition to standard sand flocking, the MDF board is also coated with a mix of play sand applied wet & saturated with white glue. The ridges represent underground tentacle growth from the infestation, hopefully the effect will be more noticeable once painted.

Looks fantastic, but I’ve always wondered since setting the terrain up at BoLSCon, why both the 40mm and 60mm discs and cut-outs?

The cut-outs were used because of the 40K 5th ed Line of Sight rules. Because LOS is specific to the actual terrain item, moving an object will have an impact on the game. By having a “home” spot for each object, the terrain has a fixed location. As for 40 vs 60 – I don’t really know…. variety?
