The bpatcher object allows a patch to show a window onto the contents of a subpatch. The portion of the subpatch that will be shown in the bpatcher window can be changed by an offset message to the bpatcher or to a thispatcher object inside the subpatch.
The bptatcher object allows you to show a view of a portion of a subpatch inside the main patch.
You can change the visible portion of the bpatcher with an offset message to a thispatcher object in the bpatcher's subpatch, and you can change the size of your bpatcher with a script size message to a thispatcher object in the parent patch.
A way of hiding or showing Max objects is to assign an object a “scripting name” in the Inspector, then give the thispatcher object a ‘script’ message telling it to hide or show that object.
To ensure finding a file (regardless of any File Preferences… settings in Max) you may need to provide the entire path to the file in the hierarchical file system: volume name, folder name(s), and file name. This example shows how you can construct such a full path.
