This material doesn’t even exist in UE4 so I’m not sure which version of the engine you had it working in.
I glanced at the material and I believe the reason nothing is appearing is because it’s sampling RT_Profiles which is an empty render target. There’s nothing to show because there’s nothing there.
I recalled Ryan Brucks mentioned generating distance field profiles from curves so I assumed that was what this is for. Looking at the blueprints folder, it is used by the BP_CurveProfileTo_RT blueprint. Unfortunately if you try to place this BP in a level, it will silently fail its validation check (silent because there is nothing plugged into the invalid output pin) and the reason for that is that there is no RT assigned to JumpFlood Result RT. If you drop this bp in a level, create a render target and assign it, then the material will work… kind of. I mean, it renders, but it looks pretty bad.
I’ve never seen this material before so I have no idea what it is supposed to look like.
