Getting a serious graphical problem from the game, when I look in the terminal it keeps trying to build the shader with no success. no matter the settings the graphics looks inverted, neon or something.

[2016.12.26-18.36.05:687][ 0]LogMaterial:Warning: Failed to compile Material /Game/RestrictedAssets/Weapons/Weapon_Base_Effects/Materials/M_LinkGun_hologram_02.M_LinkGun_hologram_02 for platform GLSL_150, Default Material will be used in game.

awhile after, this repeats constantly in yellow!
