I cloned a project that was made using Unreal Engine 4.7.6 and then opened it in Unreal Engine 4.8.0 Preview 1, I used the Convert In Place option, the conversion appeared to work fine, no error messages, however, when I looked at the Level Script Blueprint I noticed that it was completely empty, none of the nodes were transferred from Unreal Engine 4.7.6 project to the Unreal Engine 4.8.0 one.
So the nodes don’t seem to transfer over when converted.
Hey ,
I created a test template of first person and added in some nodes, which were connected to play once the game started. I then closed 4.7.6 and opened up 4.8 preview 1 and converted the project to 4.8 preview 1. My nodes were still there. Would you be able to elaborate more on what type of nodes you had in place in your level blueprint so that I can further test this and have it reported to our developers?
Looking forward to hearing from you, thanks!

Here’s a video showing what I mean, just tested it using Unreal Engine 4.8 Preview 2:

Hey ,
Is this only occurring in that one project or does this occur across the board for you? I have not yet been able to replicate this and I’m wondering why.
Looking forward to hearing back from you, thanks!
Happens with all projects.
Hey ,
Have you tried this in 4.8 Preview 3? I have created a project in 4.7.6, ensured there were connected nodes placed within the blueprint level, that worked correctly. I then saved the project and converted it in-place for 4.8.0 Preview 3. Once I did that, I checked the blueprint level in 4.8.0 Preview 3 and played the game within the editor and the nodes were firing correctly.
Thank you!
Yes, and it’s happening with Preview 4 as well, I wondered recently if it hads to do with the input axis settings because those can be exported and imported and if you don’t do that then how would the project see them?
But I did that and it didn’t affect it.
What I’m doing now is just doing new builds from scratch currently using 4.8 Preview 4 and not using the conversion tool, and simply migrating folders with content over and rewiring it all, and that’s ok for me right now as I’m keeping my projects small at the moment.
Hey ,
Thank you for letting us know that this is still occurring for you. I’ve tested it with one project from 4.6.1 > 4.7.6 > 4.8.0 Preview 4. Each time I converted the project in place, it did not lose the level blueprint. Are there specific nodes that you’re using that’s causing this, or are you getting this to happen with any and every node you place into the level blueprint and then convert up?
If you could provide me a screenshot (close enough to decipher) of the level blueprint before you convert it up, that would be helpful for me to reproduce and enter a bug in for our developers.
Thank you so much!
