Hey
Yes Sander, I think you're right, she's referring to the Fusion tab of Resolve, therefore the chain button is actually within Resolve and is not meant to work with the Fusion tab only I guess...
But hey, not being in front of it 5Fu Studio) here, you think searching with a "paths" word will easily lead me to it in Reactor ?
Because that's what I what trying to fix
yesterday 
: I was preparing clean Fusion comp files, with around 7-8 different 3D obj or fbx files - one 3D object per comp - to be able to pop them out whenever needed. Imagine when you have to relink diffuse, normals, specularity, and anything to bump maps files and finally to a cook torrance or blinn node when any path is broken !
Very frustrating when you know where all the files are gathered and stored but have to do it one by one
(and that's because I can't bake them in Blender for example, where I'd like them to be deeply and steadfast linked not to be forced to relink whatsoever)So thank you for the input
