Are you sure you don’t want to check out the BrickGame Plugin?
Because if you want a world made out of bricks like Minecraft the draw distance does not matter all that much. It will save you a bit of graphics rendering but the object will still be loaded within the same level.
Anyway. The settings for draw distance and Level of detail are in the advanced tab of “Rendering” in the defaults of your blueprint.
Click the little arrow below the “CapsuleComponent” tier and you’ll have a “Mesh” tier. Inside the LOD settings there you have a “Min Draw Distance”, “Desired Max Draw Distance” and “Current Max Draw Distance”.
This should get you somewhere.
