 So while working with MetaHumans in a new ray tracing project, I've realized that there's an issue with the eyelashes here, where they're using hair cards and that that's not working with the transparency issues with the ray tracing. So here's how you fix that. So you want to go into the MetaHumans folder. Let's go into this character. We want to go to the face. And we want to go to this face mesh blueprint. And this is where we're defining the LODs and everything here. And you can see that we've got this weird shadow effect here that's all blocky. It took me a few minutes to kind of figure out where this was coming from. I could certainly see it look like hair cards. So to fix this, we want to go into the LOD settings here for LOD 0. We want to expand the sections down. And for these eyelashes, I know that this is section 6. And so what we want to do is we want to simply turn off cast shadows here. This is what's happening. We're casting shadows of these card blocks. And the ray tracing can't handle that due to a current bug from what I'm understanding. Anyway, as you can see, we turned that off. And now it's gone. So we save it. We let Unreal do its processing here. And let's see whenever we close this out. Everything should be good. Yep. And there we go. So she's very happy now. Her eyelashes aren't causing a blocky shadow. And that's fixed. And so this is how you can make your MetaHumans work with RTX ray tracing enabled. So if you like this type of thing, make sure that you subscribe. I've got weekly videos for Unreal Engine coming up. And I'm probably going to be adding some additional programming type videos during the week. So thanks for watching.
