There is an issue using hierarchical generation in pcg using the difference node or even spatial nodes. Use the difference node to, for example, remove all grass under a tree or rocks will not continue past the cells/chunks. So it will subtract everything but then once it hits a new cell/chunk it actually does nothing which is to say the least, not very helpful. Anyone found a workaround other than NOT using hierarchical generation for grass? This seems like a pretty big issue for a lot of common gameplay mechanics. Maybe there is another step I need to do in order to get it to continue? Would appreciate feedback before I submit a bug-report. You can see the screenshot below with debug cubes turned on. The same thing works with using spatial nodes.
