Upgrading to 4.15, blueprint nodes lost their linkage

Hi, I have a suite of 7 plugins that i am trying to update to 4.15. I am having insane issues, and have rebuilt them all from scratch, without the PCH files, as is the new way. Otherwise visual studio cannot find any of the headers.

Now though, all of my (approx 300) Blueprint nodes that call my code from the plugins, have lost the link to the code.

When I open the editor, the nodes all have ERROR. Ok, so i went through and painstakingly remade every node and re compiled the blueprint. Fine, linkage restored. I closed the editor. When I open it again, the links are gone again. (I am able to recreate the nodes without issue).

So far 4,15 has rendered all my code completely unusable! What can I do about this?

Hi ,

Would it be possible to get a sample plugin that is exhibiting this behavior?

One thing to check would be to make sure the plugins are properly enabled. We did have a few existing bugs related to plugins that were fixed in 4.15, and one of those was related to the EnabledByDefault setting. Previously, this was being ignored if it was set to false (meaning the plugin would still be enabled), and some people were surprised when their plugins stopped working because now they actually are not enabled by default.

Hi ,

We have not heard back from you for a while. Do you still need any help with this issue? I will be marking this post as resolved for internal tracking purposes, but please feel free to add a comment and re-open this post if you need any additional assistance.
