I create a blueprint project from UE 5.0.3 from source and I using the PerInstanceRandom node to get the random value from 0 to 1 after that, I use this value to lerp3color function to get the random color between Red, Green and Blue, I use the Instance Static Mesh (ISM) to apply the material and this work perfectly in window preview, standalone and mobile preview, but when I update project to 5.2.0 window preview and standalone ok but mobile preview always return the red color, Im trying to replace PerInstanceRandom with constance value (0.5) and it display green this mean PerInstanceRandom not return the random value and always return 0 value in mobile preview mode, I spend an hour to research but no thing change. Does it is a bug of UE 5.2.0 release from source ?
