Hey .I import my model from cc4 to Unreal Engine 5.0.3 everythings looks ok but whatever i do hairs looks like in the image that i uploaded .To much pixeled ,low quality even with 4k .Glad to hear any suggestions
Have you fixed it? I have the same problem.
I think go to the hair material and unselect Use Material Attributes.
Hello - I know this is an old post but when you say unselect material attributes, is that a setting in CC4 or UE5 ?
Sorry, I can’t remember but I’m sure you can find it by clicking around hopefully 
You can find "Use Material Attribute"check box in Material Graph (Double click the hair material and it will take you to material Graph). To left bottom in the screen under details you can unselect the “use material attribute”.
But does anyone know why the hair from Character Creator appears too thin and how to fix it?
