I was trying to follow tutorial - simple landscape with ocean. Everything was ok. After I loaded the project again - the sand part of landscape is not visible correctly - there is not demanded texture. When the map starts, the sand is visible then blinks and gray basic matter of world appears.
I am not sure what to do or what I messed up.
Sorry, what do you exactly mean by that ?
delete landscape from outliner and create a new one and paint it again ?
surely there must be a different way, when it was visible correctly and after restart not.
