it’s a skin texture. but when it be imported to unreal engine (4.15), it change to grayscale… why???
I’ve had the same issue with some of my characters’ skins. I noticed that their is a morph curve for my character’s eyes blinking in the animations. I removed the curve, removing the blink morph as well, and the skins remaind as they should. Since I just switched to 4.15 I’m still trying to figure out why the curve is causing my issue. Check to see if you have something similar to what I’ve described and see if that fixes the problem. If not, then I wouldn’t have any idea.
