please don't freak out!
I know hair demands a lot of processing and stuff... I just wanted to try it out for fun :)
I'm just as new in blender as to godot, and I found this video teaching how to make hair in blender, but when I try to import it to godot, only the sphere is imported.
I tried glTF 2.0., DAE (COLLADA), OBJ and FBX, formats, and since none of those worked, I don't know if I'm doing something wrong or Godot doesn't support this kind of "particles".
P.S.: Btw, I tried to use better collada following the article from gamedev, but I couldn't find the addon in the list...
