What do you need help with?

I want to build the map art.
I have already got the *.schem for Baritone.But when starting to build , baritone doesn't not how to start.

Can any setting to make we can place specific blocks below the wool.

Here's the structure I want to build.

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

There is no setting to make it place blocks below a map art, but it should place blocks to place against automatically.
If you want to have specific blocks there, you have to include them in the schematic.

When set the empty to structure _void,it will act like this.
Keep searching but get nothing and will not move.

When set empty to air or void_air
,it can't even look around

Or...what type is right
I already set allowplace to true.

Here's my *.schem for three type.

air is the block that fills empty areas in the end. If you want to use structure_void you might want to have a look at buildSkipBlocks or buildValidSubstitutes (only exist in the latest 1.12.2 release).
Make sure you have throwaway blocks to pillar with, I am building air.schem right now without any modified settings.

Thx.
I lost the throwaway blocks to pillar with .Everything is fine now.
I though any blocks can be the throwaway blocks even the material at first.
