Hey, I have added a patch (to v4.0.0), of an implementation allows us to work with how Studio adds resource paths at runtime (as project Uris). Previously we've had to manually add relative paths to make it work in both Studio & runtime e.g.
<ResourceDictionary.MergedDictionaries>
<!-- Works in Studio -->
<ResourceDictionary Source="/SomeProject;component/XAML_SomeResource.xaml"/>
<!-- Works in Unreal -->
<ResourceDictionary Source="../../UI/SharedResources/XAML_SomeResource.xaml"/>
</ResourceDictionary.MergedDictionaries>
The change sets up a Namespace -> Path Map in the settings, and then uses that when looking up Uris. This is manual process though. I haven't checked how expensive that may be, doing it every Uri look-up. Let me know if you think it's a viable solution, or if there's any issues you might think it to cause.
This is more just visibility of a part solution, I would still prefer your expertise on what a final solution may want to be.
This also only helps with the runtime, there are still issues around if you want to create new Studio projects with different namespaces within the current version of Studio within Unreal. For that we currently still have to do that in Standalone Studio.
Ideally we'd want to also improve the Unreal Studio side, such as:
- Ability to create new projects under different namespaces (other than 'Game')
- Able to have multiple projects open at once, instead of just 1.
- Project list more manageable in-game i.e. most recent instead of fixed list shared by all.
