Hi, my intention is to use the static mesh or skeletal mesh as the distance field data for raymarching.
Looking at this Unreal training, link text Ryan created a material with a CustomExpression to do the raymarching, but that expression also takes in 3 sphere parameters which are SDFs. So my intention is to remove the 3 sphere parameters, use the mesh’s SDF, plug them into a Post Process to create “metaball” effect of any mesh with the Post Process material on.
Example use case: A skeletal mesh walk towards a sphere and as they get closer, they will form the “metaball” effect as if both of them extending out to pull each other in.
