FBX into Unity Help?

I hope I put this in the right category. Sorry if I sound dumb, I’m VERY new to this-- I installed VRChat and Unity today and I’m trying to use an MMD model as my avatar. I’ve already used Blender to export the model to FBX and I’ve gotten the model of Chongyun here onto the scene. How do I get those blobby colored parts off of him? Thanks!
