Hi, please excuse my English over … I first used the substance to unreal plugins … I use unreal 4.17.1 and Substance use 4.17.0.25 Plugin … when I turn on the plugins on the unreal editor and restart the editor… and it always crashes when I open the unreal … I install the plugin by copying the folder into \Unreal Engine 4.17.1\Engine\Plugins\ … maybe there is something wrong with the way I am. Please send me the instructions. Thank you very much…
