Recently, I ran into an issue where almost all the materials in my game are yellow. This includes all the landscape textures, and even Quixel megascan assets I import new. I can change the colors in the materials but the yellow tint stays (Which is a significant problem for my snow, which I can not get white). When I set up the landscape and some of the quixel assets, everything looked fine. Is there some landscape-wide color picker? Thank you for any help or suggestions!
Can you post screens of some of the materials BPs? Doesn’t sound like a matterial issue but worth checking. Sounds like it could be something to do with lighting or post processing. Does your project have a directional light or some other light with a color tint? Is your level using a post processing volume? If so maybe review the settings for that.
