In the character blueprint. I use ordinary material with one texture sampler node that created in UE5 and I made a set of node change texture of the “texture sample” node and use timeline node to create animation. I use a variable of texture array to ref to timeline and then set the value from timeline to texture sampler of the material.
My English skill is not good but if you see this video you will understand. when bliking eyes. the texture is blury change.
