4.7p4 Need help w/ collisions when importing paper2dsprites

So I happened across this amazing tool called TexturePacker and I saw it had a special export for UnrealEngine. It packs really nice sprite sheets and generates a data file .paper2sprites I was then goofing around in UE4 importing the sprite sheet and I couldn’t get it to work. On a lark, I decided to try to see what happened if I imported the .paper2sprites file. I was shocked that it worked, and worked well! I had been struggling with trying to manually align all the frames of every spreadsheet by hand. It was so slow and error prone. This new technique is instant and has been working flawless so far. I am thrilled.

But then I noticed something odd. Before when I used “Extract Sprites” it made tons of files one for each frame. This new way of importing only makes one sprite sheet. Which really is preferable than 100s of frame files cluttering up my folders. But when I double click this new sprite sheet file, I get a new sprite editor than the sprite editor I got from the old way. This new editor doesn’t allow me to edit the collisions anywhere I can see. So I need help! Is the collision editing hidden somewhere I can’t find? Can it be made to open these sprites in the other editor that allows for collision editing? Heeeelp, I really don’t want to go back to manually fixing every frame of every sprite!

haha, derp. I found a sneaky frames sub folder where it was hiding all the sprite frames so I can edit as normal.
