Hi guys, is there a way to make a decal that doesn't repeat? I want to overlay a hand-drawn map onto the terrain so I can paint my height contours but the decal always wants to repeat/tile (depending on the terrain size).

I've tried changing all the settings in the Decals property window (both of the decal instance and the RootTemplate), but these seem to have 0 effect.

I can fiddle the material itself (changing its UV tiling or adding a multiply to the UV before sampling), but the decal still repeats, the UV manipulation applies to each individual tile.

Any help would be appreciated (including a better/alternative way of tracing a map using the terrain tools).
