All my rules work perfectly, but now I have a situation where I want to automatically create a wallshadow in a corner depending on what surface is in my back_default layer. This means I need 2 input layers. A default input layer which has the wall tiles, then a back_default layer with a surface behind 1 of the walls. After creating a rulefile like this, all other rules stop working as well. The paths in the rules.txt file are correct. I’ll show a few pictures of my rulefile.
The result is that it adds shadows based on the surface:
Is there a way to achieve what I want? Thanks in advance.
