Adding a png to the floor #6922

Yes, this is possible.

The usual way is to apply the PNG as a texture to the floor geometry by using an ImageTexture inside the material/appearance of the floor Shape.

For example, you can use something like this:

Shape {
  appearance PBRAppearance {
    baseColorMap ImageTexture {
      url [
        "../textures/my_floor.png"
      ]
    }
    roughness 1
    metalness 0
  }
  geometry Plane {
    size 10 10
  }
}

A typical project structure would be:

my_project/
  worlds/
    my_world.wbt
  textures/
    my_floor.png

Since the world file is inside the worlds folder, the texture path would usually be:

"../textures/my_floor.png"

If you are using Webots' built-in Floor PROTO instead of a raw Shape, you should check whether the PROTO exposes fields for appearance, texture, or tile size. In that case, it is better to set the texture through the available PROTO fields rather than replacing the whole floor manually.

Also, if the image looks stretched, you may need to adjust the floor size, the texture size, or use a repeated/tiled texture depending on the visual result you want.
