Every Material has a Yellow Coloration

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.

Thank you for the suggestions! Unfortunately I am not using any post processing volumes, and the directional light did not seem to have any yellow colorations set (screenshots attached).

I checked in the Env Light Mixer settings - are there any other locations that might have that info?

Outside of lightning, I noticed in your original post the image texture and material look very yellow, have you tried adjusting the color values in the image itself( if you open the image in engine you can adjust things like brightness, hue, saturation ECT ..) or in a 3rd part image editor?

I will have to try using a 3rd party program. Unfortunately it will be quite tedious to change every texture individually. I checked the master materials and none of them seemingly have any yellow tinting. Interesting it is only the landscape and the rocks that are yellow. The grass and trees are fine.

Yea I noticed the base image file for the rock texture looks super yellow, not sure if other texture files are like that too …unless you do some runtime color correction via the material(Wich I wouldn’t recommend for performance) you got a change the hue of the image, you can do this by opening up the image in the engine, but the tools and settings are limited.
