Meaningless Mesh Size

I have tried to implement the code below but the result does not make any sense for me. Could you please lead me about the usage?

The mesh is the one in blue.

Solved. There was a formatting issue. There was no problem with the returning values but with the formatting keys. Instead of using ‘%d’, I had to use ‘%f’.

Wrong Version:

*FString::Printf(TEXT("Ground Extends x: %d  y: %d  z: %d"), GroundExtends.X, GroundExtends.Y, GroundExtends.Z));

True Version:

*FString::Printf(TEXT("Ground Extends x: %f  y: %f  z: %f"), GroundExtends.X, GroundExtends.Y, GroundExtends.Z));

The main reason is that those variables are float numbers.
