I have OoT3D, and I recently discovered RBA and the coloured gauntlets. Some of you might guess what happened already... I got the Purple Gauntlets. Then decided to finish the game 100% (for a challenge). However, when I got to the Spirit Temple, I though I'd have some fun with my gauntlets and did the adult section first...
And now, I can't access 2 small keys, which blocks my progress in both wings of the temple. To get them, I'd need to unlock the door between the child section and the main room; however, the small key that can be found in the entrance room was used for an adult locked door. As a result, I can't access the hookshotable chest in the child section as an adult, and I can't access the corridor with the silver block as a child (the small key there isn't present when you're adult).
If I had the original, I'd probably hover up the hole in the ceiling of the entrance room as a child (where you normally hookshot as an adult), then clip through the silver block and access the small key. Then unlock the door from the main room to the child section, then come back as an adult and get the hookshotable chest and continue. But in the 3D version, clipping is very hard, if not impossible in most places, and I can't get ISG to work (is it even possible?).
Of course, I could get the spirit medallion with RBA, but then I won't get all my Golden Skulltullas.
EDIT: I just found the OoT3D section of this site. Now I feel dumb
Anyway, the hookshot clip should work fine. Thank you to everyone who tried to help me.
