You are right. One day a customer told me to add some -moscovia flowers- into her map, but, the flowers were textures placed in ground edition.
... So with this tool you can cut those terrain areas, and make custom models of those flowers! I know, perhaps, it is a bit weird, and there are other simplest ways to make it, but there you have an example.
Also what you said it is true. You can take a bunch of ragnarok flowers or models, and merge it into just 1. So you can save time instead of using -Group Model Edition- in browedit, which it is useful, but it is hard to handle the models in group mode, for example, flip them.
