In my current contemplation how to make easy add on terrain bases for Heroscape, I have stumbled over some people making custom pieces using resin casts of the Heroscape basis pieces.
I was thinking before about buying water-tiles in bulk and using them as basis for rough Terrain, Buildings, forests etc. But did not know how to solve the issue with larger buildings. John Backwell had a great idea with his polystyrene Triangles, but I would prefer something that interlocks the same way the rest of the terrain does.
Now I have seen that some Heroscapers did just make a mold off of some terrain pieces to create their own unique tiles. Does anyone of you know if that is a legal option as long as I only use the stuff to make my own terrain (no marketing, selling or use for commercial purposes). It just seems to be ideal.
