    Hello guys, maybe it's late, but i made a tutorial for developing plugins using the hot reload feature. I'm using a workaround for that (creating game modules first and converting them to a plugin later).

    Even cold reload doesn't always work. Sometimes if you add or remove parameters to a blueprint function defined in a plugin, the node in a blueprint will not update. :P
    Then you have to delete Saved and Intermediate folders and do a full rebuild.

    It seems I cannot find this "Modules development window" under Window -> Developer Tools. Is there a reason why?

    It would be very appriciate to have possibility for hot reloading plugins just from VS. I do test on Actor in UE 4.10.1 and it seems that it is not working.

    Usually Recompile in Modules development window should hot reload plugin.

    Are there any news on implementing hot reload for plugins? I heard in the latest stream, that there will be some updates for the plugins system in 4.8. Could it be, that hot reaload will be out with it?

    Hot reload does not work with plugins, this is true. However, you can recompile plugins in-editor. Go to Window->Developer tools->Modules and find your module. Click Recompile and it should hot reload your plugin.

    You may not have this window in a content-only project. Some things can not be hot-recompiled, such as some Slate functionality.

    Plugin development and hot reload not working

    Ok, so this is somewhat annoyingly painful: I'm developing a plugin with Blueprint functionality. The hot reload simply does not seem to work with plugins, when I add a new UFUNCTION to my UBlueprintFunctionLibrary it does not appear in the Blueprint editor after hot reload. As this is my first ever plugin it took me hours to figure out what I was doing wrong (that is, nothing!) - you have to restart the editor in order to see any plugin changes. This is a really painful workflow, restarting the editor to test changes, I really hope this gets fixed.
Working...
