After playing with Voxel Map on all earlier versions of minecraft, for some reason, I can't seem to get it to work on 1.14.4. Xaeros minimap was the first one I could find and get to work, but it's frustrating. I really don't like a lot of it's features but until I find something better or get VoxelMap to work I need some info.
What distance, up or down, is the cave mode showing?
In Voxel map it shows nothing below your feet and shows any voids up to about 10-12 blocks above your head, Now in Xaeros I see a mineshaft and went over to it. I mined up 15 blocks and down 15 blocks and still can't intersect it.
Why does the minimap free north but locks it if you ask for expand?
Lastly, what is a better minimap to try although I'm still hoping on VoxelMap
I'm using Java version of minecraft on Mac OSX 10.12.6
Bibliocraft is not strictly a minimap mod but it provides a map item called the Atlas that creates a minimap from the vanilla map items stitched together automatically. It's pretty nifty, but I don't think it's as functional as one of the above dedicated mods.
I don't know how many of them are updated to 1.14 yet, or if so how stable they might be, but Xaero's and Journeymap always seem to be leaders of the pack.
