Same material, different colours

Hi all,

I have apply simple material with texture to wall static mesh and have different colours.





Appreciate any help

Its probably the light thats making the color look different.

If you want to make sure, disable all your lights and add only one point light in the middle and set it to pure white, should help seeing if it is the current lighting setup that create issues with colors, because it can be because of bounced lights.
Also, always remember to aadd a node to both metallic/spec and roughness, can be a simple 1 vector for both.
