Texture brush node which is using with UMG components converts your texture input to slate brush variable. This means you can set your slate brush variable or change in run-time on Reality API.  

How to use Texture Brush

  • Use  ADD NEW button > User Interface then select Widget Blueprint.

  • Select Graph tab, open class settings and set "Parent Class" as "ZDRealityWidget" which under Details Tab.

  • Select Designer tab, add an image from Common section under the Palette and check "Is Variable" selection.

  • Open Graph tab. Add new variable from Variable section. Select it as "SlateBrush" variable.

  • Make it public. Click eye icon.

Reality API detect automatically your "SlateBrush" variable which created in Widget Blueprint. You don't need do anything except make variable public.

  • Create code block with blueprint. (Basically, we will set "MySlateBrush" variable to "myImage" with  SET BRUSH node.)

  • Export your widget Blueprint from Edit > Project Settings > Exports. Add new export value under UMG > Widget Classes. 

  • Everything is ready for Setup API. Click PLAY button. Open Reality Setup.

  • Add an UMGRENDERER node

  • Select specific UMG class on Widget property from properties of UMGRENDERER node

When you set your widget class, your slate variable will appear on UMGRENDERER node


  • Add a "CheckerGenerator" for basic input from Create > Generator > Checker Generator. 

  • Connect nodes as shown in the below image.

  • Let's see the result.
