Please help me!

Do what it says… You can’t really have objects located that far away from the origin.

–Eric

when i do that(changing the position), my object disappears.

As you can see the object with coordinates like (40000,123452,20235) your camera seems to be at the same Position, try Setting your object to 0,0,0 and then double click in your hiearchy on it, so unity zooms to it. now you should be good to go with your Project.

Big thanks Mr. asd234w4r5!

Merry Christmas!!
