I’m currently trying to create a way to have a creature paint along the floor as it walks and also have the player then erasing that colour but I’ve run into two issues, Currently I have my creature drawing a line behind it and I can also interact with the floor and paint the same colour on but I have 2 issues:
-
I can’t figure out how to get an eraser to work, I’ve been using this tutorial mostly but I can’t figure how to add that function.
-
For some reason my paint isn’t just a block colour, it has either a random coloured border or inner part and I think it’s due to the material nodes using LERP or Multiply? But I’m not sure how to change it so it’s just a block colour. (The image is supposed to be Grey floor with Green paint.
