Hi, already posted this in beta forums, so I'll repost here. I really think the" share as" wizard (and window), aka rpk creation needs a rework or at least investigation upon some issues.
First of them is: it's really slow at compressing data (x20+ compared to a rar or zip archiver), only difference is the writing of the xml resolve map, which is quite quick.
2- the weird latent 2Gb limits is still very annoying, (rpks can nonetheless exceed this weight without notice but they won't really work in other tools/plugins (ue, houdini etc)
3- the tiny window to select/add/remove assets which should or shouldn't be put inside the archive lacks a lot of functionalities (filter, reorder list, tree view (everything is flatten in this view), there are a lot of room here to improve ux/ui, especially when trying to extract some rpks out of complex (crowded) workspaces and thus having to pick relevant dependencies
4-once created it should be possible to edit the .rpk (ie remove/add some assets) so the resolvemap could be updated. For the moment it's a task that has to be done by hand or script elsewhere.
