@masterneme: I have described one way of having a unit with multiple skeletal meshes here. This is a pretty basic implementation, but it should provide a good starting point. I have experimented with creating a Grimrock-style dungeon crawler with the toolkit before, and it works okay, but would require a lot of work to function well enough for a complete game. If I pursue this avenue again at a later point I will probably do so as a standalone marketplace assets as the differences are too big that it would make sense to build it on top of ATBTT’s framework. A lot of ATBTT stuff would not be of interest to someone making a first person dungeon crawler and the other way around. I think it will be better for the user to have a marketplace asset focused on the sort of game they are actually creating.
@: Are you using heightmaps from tracing? If you are you can have the area you do not want to be walkable to ignore PathTrace in the collision settings to prevent it from being walkable.
