Hello: I am trying yo fix cooking error also. And someone is asking for my LOG. I havo no idea how to get “My LOG” or where I can find “MY LOG” would you be able to tell me how or where I can find my LOG…
Someone said I will find it in but I am including a screenshot of my proyect and I do not see it… can someone help me please… I have been with this problem for more than twp months…
Is there a video on unreal, or youtube, that shows?
