Hi,
Well you need to add mapping to your floor,
Select the floor, click Apply Box mapping
Choose BoundingBox, then CPlane, then Yes
Now if you want to control the repetition and scaling of the texture manually
Using your Gumball click Show Mapping
You’ll see a dashed yellow boundingbox around your object, you can use your
Gumball to move it around, scale it, and rotate it
If you don’t want to use it anymore click Hide mapping
You also have a numeric way for controlling your mapping
