This is my first time creating a custom map with the Hammer Editor and everything seems to work right.. that is until I tried using the blending tool. Refer to the gyazo link for a picture.
For whatever reason, my painting/blending tool does not what to paint over the default green terrain. For example, in the orange circle I can't paint/brush anything on to it. In the yellow circle, I can't figure out how to make the tile edges smooth.
This could simply be my own fault for not knowing how to use the editor correctly but I have tried following the tutorials here: https://developer.valvesoftware.com/wiki/Dota_2_Workshop_Tools/Level_Design/Tile_Editor#Material_Sets_and_Transitions
Any help is appreciated.
