When inserting a texture, it inserts too large.

I started learning recently, so my skills are lacking.

When inserting a texture, it doesn’t look smooth because the texture is repeated many times.
The texture doesn’t repeat, it’s oversized, which looks odd.
Please tell me how to naturally apply texture to objects, walls, floors, etc. like everyone else. please

The demo levels in the engine are made out of very stretched cubes, so when you put material on them, it looks very big and stretched.

If you want to be able to scale the cubes any way you like, and still be able to drop materials on them, you need to use a ‘world aligned’ material
