Increasing landscape tricount?

Heyo! Good day to everybody!
Today I stumbled across one tricky issue: increasing the landscape’s detail level, aka having more, smaller quads/triangle.
I would like to use UE4’s landscape sculpting tools for my project, but I can’t seem to find anything in the engine itself.
Is it possible?

Either try the “change component size” tool with resampling or change the scale of the landscape. Default scale is (100,100,100) for XYZ, which means the vertices are 100 UUs apart from each other at LOD0.

Thank you so much!
