Project conversion to 4.7 freezes at 95%

Hello,

As advised on the forum, I would like to share my story. My old project, when I try to convert it to 4.7, freezes at 95%. Unfortunately, I don’t know which logs would be interesting if there are any. I use UE4 on a Mac by the way.

The project was just a toy project, I just generate procedurally generated road system in C++, then I map this logic to actual 3d meshes and populate my level. And that’s basically it. Nothing fancy, no behavior trees, no custom materials (though, there is a BIG navigation mesh). The problem is that I can’t do the usual process of “cutting down features until it starts working again” because the editor just won’t start…

Hello Fezvez,

If you still want to try cutting out assets/features/components to isolate the problem, you could go to the directory the project is stored in and remove them from there. It’s going to result in some errors, naturally, but if you find the problematic asset that way it should allow you to open the project If you prefer, you could even remove the potentially-problematic assets/features/components from the 4.6 version of the project and then convert that copy to see if that fixes the problem.

Another solution would be to try ‘converting’ the project by creating a new project in 4.7 and moving assets over individually.

Let me know if that helps.

I am trying it right now (note, it still bugs naturally in 4.7.2)

Any word, Fezvez?
