8mod maps farming strat question.

I was trying to set up idols for dropping 8 mod maps but I failed miserably. One map dropped. I am doing something wrong.
I want to farm 8 mod maps on jungle valley like I was doing in normal settlers but I cant figure it out.
If anyone have working strat for this, please share. What scarabs are used and idols setup.

I was using 3x multitude, corruption and the one for more maps per map mod. In settlers I had this with shrines on map device and atlas, also with blue altars. This event it does not work for me.
