I have a fbx character. When I import it in Unity, I have this result
While, when I import the same file in Blender, I have this result.
In the second image the are a many polygons and I don't understand why, since the file is the same of Unity. How can I get the same result as Unity in Blender? Thank you.
I've encountered this before, my easiest fix is to recreate the materials on the model in Blender, unassign the existing materials, and apply your new materials. You could also go to the existing materials' properties and find any anomalies, but that takes some time, and I haven't done that.
I wish I could explain exactly why this is happening, but I don't really know, sorry. If anyone does have an explanation, I'll be glad to edit it into the answer.
