    Bump, this is a feature I really want. There's currently no viable way to achieve this as far as I know

    Did anyone from Epic have a look at this thread?

    Agreed, the lack of spline decals in UE4 is beyond frustrating, notably for creation of roads & paths. The current spline mesh system is great for procedural walls and such but it is an inefficient solution for roads because of the gridded terrain/landscape system. Cryengine and even Torque3D have had this feature for years now so I do not understand why it is such a low priority with this engine. Every time this subject is brought up in a new thread on these boards, there is absolutely zero feedback from an Epic representative, which is depressing.

    Any Epic words on this massively important feature request?

    But mesh decals don't "project" flatly onto a surface the way normal decals do, so decal splines would still fill a purpose that is missing currently. I desperately want spline decals as well.

    Mesh decals work with the spline the SplineMeshComponent.

    and btw +10000 for this feature .
    It was on the road map ages ago, on the backlog. I can't find it now...

    I'd love spline decals as well.

    Spline Decals?

    Hello,

    I'm rewrote the OP to reflect what this thread has been through. 5.9.2017

    How many people need Spline Decals?
    Almost everyone. It's the most wanted feature by the UE4 community. Check out the link below!
    https://issues.unrealengine.com/issu...nt=&sort=votes

    Why people need spline decals:
    It saves everyone tremendous amount of manual work and tweaking, it can also be used for many different purposes. We've also done a comparison between Spline Decals and the current Landscape Spline Tool.
    https://forums.unrealengine.com/show...l=1#post701303

    Example of Spline Decal in Cryengine:
    https://www.youtube.com/watch?v=Tb60V05bg1U And documentation http://docs.cryengine.com/display/SDKDOC2/The+Road+Tool

    What features would it benefit from:
    1. Blocking Grass Tool from distributing meshes within the spline width.
    2. Remove painted foliage that are within the spline width.
    3. Displacement. With spline decals supporting displacement mapping (overriding landscape's displacement map) we can make non-destructive changes to landscape if/when landscape uses tessellation and displacement mapping. If displacement mapping on spline decals come true, it opens the doors for many more uses on landscape besides projecting a material on a surface. (This is more important than the other 2). Spline Displacement should support collision (or better say landscape collision should update to cover the deformation caused by spline displacement) otherwise we'd go through the raised/lowered areas.

    Thanks!
