Why the texture appears like this without repeating

whi t

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

Hello - you can set the texture to use world coordinates - then you get to set the size explicitly, rather than work out a repeat.
