Q & A

  1. Richard (verified owner)


    For the tiles that are adapted from the non-square predecessors, did you intend for the slight lip around the edges? I envision using these to create underground rivers/lakes, but the lip would kind of break that illusion, and it isn’t on any of the Rampage Original stuff like the Thermae or Sewers. Thanks!

    • Matt Barker

      The lip is so that you can paint it and pour in translucent paint, like liquid water by woodland scenics. Its easy to cut off if you don’t want it.

    Cool (vis-a-vis the lip question). Of note, I was loading up the watery tiles, trying to decide which and how many to print, and I noticed that the U and V are the same stl (when in the pictures they look different, they both look to be the V tile, which is the watery K).


    • Matt Barker

      Ill render out an index with some examples so you can see the difference

    Is there any difference in the A and ZB tiles? I can’t seem to find any difference between the two of them in CURA.

    • Sam Campbell (verified owner)

      The A and ZB files are exactly the same. We will adjust the set.

    Any chance you could add an open water tile to this set like you did for the non open lock cavern set. Also edges for the tiles would be awesome just and inside corner edge and a straight edge one tile in length to simulate large holes in the floor. Love your tiles sets! Cant wait to see what you do with Hagglethorn Hollow!

    • Sam Campbell (verified owner)

      You can download the open water tile from for free and there are other sizes as well. It’s called “E-TRP-v7.5.stl”. The R and U files would be really useful as well.

      We’ll add the edges idea to our ideas queue to check if/when we can develop those.
