Please tell us how to get and download the “Substance 3D for Unreal Engine”
It is not possible to get and download via fab. There is no download. It is not in the library. It can not installed manually. It does NOT show up in the launcher. It does not show up anywhere and can not be downloaded 100%.
Substance 3D for Unreal Engine is NONE EXSISTENT as of that! I can not open my old project as of that!
At least it doesn’t seem to be a general issue. I was able to select the plugin in the launcher and add it to an engine version. Do you get the same error when you try to install other plugins?
Other plugins seem to work fine. The launcher somehow thinks it is installed or available on my disc, but it is not. It does not download, because it think it is there. I don’t have it and when I want to install it fails.
In the launcher there is that overview of the installed plugins below the icons of the installed engine version. If the plugin appears on that list, try to uninstall it. Else you may have to clear the launcher’s cache.
