Meld v1.3.0
Guided start, live tuning, and a benchmark report.
1.2.0 made builds offline and fast. 1.3.0 makes Meld easy to drive, tunable while it
runs, and finally measurable. The right rail is one numbered, guided flow, you can
retune a run while it runs, and every run leaves a benchmark report behind. No engine
change (same Arnis fork 2.9.1); existing worlds and settings are untouched.
Highlights
- A benchmark report for every run: meld-report.html + .json next to the world, with
your machine (CPU model, cores and threads, RAM type/speed, drive type), the run
settings, CPU/RAM and activity graphs, a per-worker cell timeline with replay, and
Save as PDF. Written on stop too, so a partial run is still saveable. - Tune it while it runs: change workers, threads per worker or CPU budget mid-run and
the next cells use the new numbers. Origin, seed, elevation and scale stay locked. - Explore mode: a map toggle that hides the cells, shows the world border, and turns
the map into a coordinate picker. Click anywhere for the Minecraft teleport command
for that spot, with a place search to jump around. Works before you build. - One guided rail: a single top-to-bottom flow, steps 1 to 6, advanced cards at the
bottom. Fast first-build defaults (1:10 scale, buildings off, solid ground), a
readable scale, and a free 1 to 64 cell size. - Accurate gauges and a smarter Recommend: CPU% from a background sampler (it was
reading near zero), RAM as the "in use" figure, and Recommend tunes both workers and
threads so workers times threads fits your logical CPUs. - A snappier UI: event-driven polling, instant Stop, one-Browse folder pickers.
