    So I got this idea to make triplanar decal shader.
    Just slapping triplanar node into graph was not enough since it will only work in a projector direction, and sides are going to be stretched.

    I guess I need surface data to make it work as intended.
    Any ideas to obtain position and normal of pixel a decal is projected on.

    Hi, after almost a year I'm bumping my own post.
    Is it possible to have a Triplanar decal shader in HDRP at all ?

    Is there no way to achieve this? It is pretty annoying that there is no way to "wrap" some decal around an object.
    Say I want to display a target icon onto something I shoot at, when that thing is a cube, the texture will stretch out on its sides when the projection comes at the direction of one of the normals of the cubes faces.
