Getting the Size of the Static Mesh of an Instanced Static Mesh

Hi guys,
I’m very new to Unreal Engine. Nevertheless i’m trying to make a game similar to minecraft. To do that I’m using c++.
Currently i’m working on getting the terrain generation just right, but I’ve run into a little problem. For the Terrain I use an Instanced Static Mesh, where I specify the Static Mesh it should use in a blueprint of the c++ class.
Now my problem is, I want to get the dimensions of the Static Mesh, so i can scale the terrain perfectly. Is there any way to do this or do I have to specify the Static Mesh in c++ itself? And if so how do I do that?
Thx in advance :slight_smile: .
