What TaleSpire said about your packs
1 Map image
Tone alone cannot tell a table drawn in shadow from the empty page around the map. Cutting the background out settles it, and the map then reads by its transparency rather than by how dark things are. The first cut downloads a model, once.
2 Scale
Nudge the pivot until the drawn grid and the overlay line up. Whatever sits before the pivot is margin, not map.
3 Read the map
Instant and free. Floors keep their cells; walls are drawn as lines on the boundaries between cells, because that is what they are.

Which asset packs to build from
Leave the sci-fi pack out of a dungeon and a search for a crate stops answering with a sci-fi crate. Changing this rebuilds every theme.
Click any of these to change what that label is built from. The search runs over every asset in the packs you ticked, ranked the way the theme's own words were — so it starts where the automatic pick left off. Give a label several pieces and the map draws from all of them, spread by position, so a floor stops repeating. What you choose is remembered.
Click to add a piece, click it again to take it away.
