Can't raise individual vertices from the Creating a Height Field Painter with Blueprints and Render Targets Tutorial

I’m pretty sure I followed the directions exactly (save for the missing assets and texture for MAT_Heightfield_Painter - see [this post][1]). I also made this minor change in MAT_Force_Splat as UE was yelling at me, but I doubt that would be the cause of the issue:

I tried manually tessellating MAT_Heightfield_Painter and moving the link to “World Displacement” instead of “World Offset”, as this is normally how I would change the position of individual vertices, but that didn’t work either. I tried my own 100x100 plane, as well as PlanarReflectionPlane recommended in the linked post. I also changed BrushSize to .001, but that had no effect either.

I figured it out, and this was due to a misrepresentation of the image for the Construction Script: it says to have the parent be ForceSplat, when the material that we’re supposed to make is called MAT_ForceSplat… and it just so happened that somewhere in my assets I had a ForceSplat material that I accidentally used instead. Changed this to MAT_Force_Splat and everything started to work as intended.
