[QUESTION/REQUEST] Instancing improvements

Is there currently a way to use instancing only with the surfaces you have selected on the parent object?

It would be great if I could select faces and have an instance applied only to those faces, rather than everything in the object.

Also, I notice when I use instancing, that I create the first instance then apply these to a surface, the original instance is still lingering. I have tried deleting it afterwards to clean up the scene but the node turns red. It would be nice if you could set a flag to use the first instance as part of the instancing procedure.

查看 Sorcar addon 中的实例化节点逻辑，相关代码可能位于 nodes/instancing.py 之类的文件中。了解当前针对整个对象与选定面的实例分别是如何生成的。查阅 Blender 的 Python API，了解面选择和实例放置。目标是修改该节点，使其遵循面选择，并可选择将原始实例作为处理过程的一部分消耗掉。
