Level blueprint save on compile issues, no save button on bar
I am on UE4 4.7 preview 4. This took a few hours to figure out. Was a simple matter. Basically when working on a fireworks show I would make changes for when the fireworks would shoot off in the level blueprint and I would preview it with "VR preview" everything was working accordingly.
But then the problem: When I would package the project no changes from my level blueprints would take effect. Even after saving my entire project.
Well, It ended being an issue in the level blueprints section under the file menu, the "save on compile" setting. It is by default set to "never" and is greyed out. It also also buried deep in there, there is no save button on the top bar here like in other sections. (at least on my screen) so my assumption was it was auto-saving on compile.
I had to go to file "save all" then the changes would finally take effect in the packaged project. This seemed a little counter-intuitive as I had saved the entire project but it would not apply my level blueprint changes on packaging.
I am not sure if this is a recent bug? I still can't change that setting to auto-save and somtimes I forget to go to file, save all.. but perhaps that should be set to default. I feel as though when you package a project it should know to autosave the level blueprint, and have the same behavior as the Editor preview options, and apply the updated levelblueprint to the package. I spent a good amount of time messing around with maps and modes and various game modes trying to figure out the problem. Just want to give a heads up.
Thanks for the feedback! I agree that this might be confusing, so I have entered a feature request to add a Save button to the Level Blueprint Toolbar for the developers to consider. I will let you know what they say as soon as I get an update.
I was not able to reproduce the greyed-out Save On Compile option, however. Is this still occurring in 4.7 Preview 7? Is this happening in the binary build from the Launcher, or have you built from source?
