1 - draw a room

2 - apply a texture to the floor

3 - don't like the textures?

- search a tile that you like and save it to your computer

- edit the room and do as if you want to apply a texture
- on the right side of the window, click on IMPORT
- import the texture and set its size
- use the texture you just import

That's all. Success!
