I decided to try the GpuLightmass plugin, I couldn’t get it to work well but I don’t worry because it’s in Beta.
The problem is that now when I back up with cpu, it does it incorrectly and the preview lighting in the workspace also stops working.
So I decided to disable the GpuLightmass plugin but it keeps doing the same error. I also tried to create different projects and it is activated by default.
I ended up uninstalling the program and deleting all the Unreal files in Programs File, Programs Filex86 and Appdata but when reinstalling the program the plugin appears installed and activated by default.
I also tried to install Unreal on another computer, and the same thing happens, the GpuLigthmass is instaled and activated.
I just wish someone would tell me how to get Unreal completely back to default.
Thanks.
