You should copy the texture from the terrain paint and make a new pattern. Then you can apply the pattern to the floor tile in your game. To copy the texture, open
S3OC and select cloning > terrain paints, then find the one you want and copy the texture. Then make a new pattern and give it the texture you copied from the terrain paint in s3oc. I hope this isn't too difficult to understand.
To learn how to make patterns, view the "Patterns" forum.
