redish tint mesh

hi i hope everyone is doing fine.
I’ve started unreal a week ago and had my share of problems, the most recent one is that some on my mesh have a red tint to it, even if there is a material applied to it (i’ve put the same material for everything those mesh are still reddish)
(i’ve turned down to low intensity all the light and turned off the fog, with all the normal settings, the tint is beige and not white has it should be)

Does anyone have the solution to this?
