Can I update my unreal project from 4.15 to 4.18 without problem

Hi, I seem to have an issue with my unreal 4.15, namely that for no reason whatsoever my unreal does not seem to recognize any gamepad input and it happen like one day it worked and the day after it does not.

I guess I could simply reinstal my version of unreal but If I download and instal a new one, will there be a compatibility problem? Like some of my blueprint node will be obsolete ?

Thanks

I would say that if the gamepad isn’t working then it won’t work even if you upgrade (although you could test that without migrating your project)
I’d see if you can fix the gamepad issue. Otherwise if you really had to move to 4.18 to get it working then there’s definitely a possibility that something you made stops working correctly, but if things are fairly simple then there’s less of a chance of that happening.

Its a strange issue but I can assure you, the thing was like a day it worked the next day it does not and the little modification I made between those does not have any incident or relation with the game controlle. The engine just does not register my gamepad anymore, neither on the menu or ingame and I tried my gamepad after that with other game and it still work fine.

If you are migrating your project for 14 to 18 you wlll have to rebuild your input table or export it from the .14 project over to the .18 project,

To update the project you should be right clicking on the project file and “switch unreal engine” and select 4.18 from the drop down. .
