There is a bug that let Djinni crash when you create a placeable in the cutscene editor. So I recommend to open a area and place for example a m0_blocker01 somewhere (at best a place the player could in game not see). Open its properties and change the model name to that of the item you need. (With the pictures you can download
here, you find the name) Now save the module and open your cutscene. Click on the placeable/item and
inserte a hookpoint and a parent at 0. Click the hookpoint and chose the part of the characters body the item should be hooked (for example
rhand) on. Click the parent and choose the character the item should be hooked on. And your character has his item.
