Creating brush using render target is not working

[MatinhoFS]

Hi,
What I’m trying to achieve is painting the landscape in game using brush. After set up blueprints that you can see below, it’s just applying color/texture to all landscape instead of painting. Tested in UE 5.1, and 5.2. Also I was trying to do similar effect with Virtual Textures, the same problem (applying color to all landscape in one time). This blueprints is basing from YT tutorial: Building High-End Gameplay Effects with Blueprint.
Also if you guys know better way to painting landscape in game like in first person farmSim games, please let me know

So I solved my problem, brush material needed part of structure that you can see below, previously I replaced it with a noise texture because it was not working and render target was just showing black color or other color on the entire surface. That was because of terrain was not placed in 0,0,0 so it is very important to have terrain at 0 location and also set up good coordinates values on textures and on render target ;).
