Unreal Feature Request: Detect and combine custom UCX collisions meshes with their owning mesh so that collisions can be batch exported

[PecakePie]

Creating custom collisions is an extremely common, and often necessary step in the asset creation pipeline. Not being able to export them as part of the batch unfortunately limits this tool past a certain point. Adding this feature would make this addon--already the best batch exporter addon available in my opinion--about a million times better! Thanks.

hey, i'm looking into this this weekend. really like the idea! unrelated to this how do you create those collision meshes, do you do it manually? shrinkwrap or decimate modifiers? do you use an add-on? thanks

Thanks for looking into it! I make collisions manually. Since collisions are almost always boxes or cylinders, they're very easy to model. Decimating doesn't really work for making UE collisions because a big limiting factor for them is you can't have any concave shapes, or the concavity is filled as a plane in UE. This means it's not a simple question of making a lower-res version of the model, you also have to break it into convex shapes. I haven't looked too deeply into collision generating addons, but I remember trying a few free ones and didn't find them super helpful. Maybe there's a good one out there somewhere though!

hey i've published a release based on your suggestion, let me know if it works or if there's some tweaks in should make!
