Hi,
We're trying to use the mix and match example script using attachments, but can't get clearing the attachment to work.
In our example, we can change the equipment and set attachments without problem. But we can't remove by setting the slot's attachment to null. The second image is what we'd like to achieve (hiding the shoes completely)
Here's the code we are using, we equip the shoe which works but when we try clearing the shoe we are stuck with the red shoe (which we just equipped).
