This is a modular low poly pipes set, just export from maya to Unreal engine and you'll be able to put pipes everywhere.I also provided the substance painter's project, so you can modify and export the textures and choose the resolution you like.In unreal engine use vertex snap to building your scene.

You'll find in it seven groups named:

AccessoryPipesSpecial piecesBoilerpumpElectric BoxesValves

When you'll import your model into unreal engine, create 7 folder for these groups, with the same name, and a folder for materials and textures, just to keep everything clean.The materials must have the same name of the groups, for example:for the group of models named Valves, you'll create a material named Valves_mat, and then you can assign this material to the group Valves and do the same thing for the rest of them.

Watch the movie that I provided!Have fun!!
