How can i use automapping to a set of blocks without region?

I can use automapping and set rules for one block. But if i want to output a pattern which require multiple input block. Do I still need regions layer?
English is not my first language so it’s kinda hard to understand.

For Example, here is my input, no regions layer

and here is my output:

Look like it doesn’t work in my map.
Please help me. Thanks!!

No, you do not need a regions layer at all.

In what way does the rule “not work”? What does your input (on your working map) look like? Your rule looks for a 1x3 area of that tile, surrounded by empty cells. If that’s not the scenario in your map, then the rule won’t match and won’t output anything.

Look like they was overwritten by another rules. Thank you. It’s fixed.
