Hi, Trying to package my game but having a problem where an error pops up with “PackagingResults:Error: Error Unknown Cook Failure”. This is my first time packaging and cant seem to find any results which will solve my warnings. I have deleted the materials that i had scene texture node in but the same warnings are popping up and the packaging fails. If more information is required please let me know. Thanks in advance! Tadas. Warning output log LogMaterial:Warning: Failed to compile Material /Engine/BufferVisualization/BaseColor.BaseColor for platform PCD3D\_SM5, Default Material will be used in game.

Hello TadasJunknevicius, The “PackagingResults:Error: Error Unknown Cook Failure” message means that there was an error that occurred that caused the packaging attempt to fail but doesn’t give any information on what the actual error is. Whenever you see this error, you need to use the Find feature (ctrl+f) to find the word “Error” and “Warning” throughout the log to find out what the actual problem is. Unfortunately it doesn’t seem that any of the messages posted here point to what the actual issue is. Can you please upload the full log file from this packaging attempt? It can be found in the project’s directory under Saved/Logs. ---
