Open the scripting tab in blender and add this script:
import bpy
def has_zero_vertices_and_faces(obj):
if obj.type == 'MESH':
if len(obj.data.vertices) == 0 and len(obj.data.polygons) == 0:
return True
return False
for obj in bpy.context.scene.objects:
if has_zero_vertices_and_faces(obj):
obj.select_set(True)
else:
obj.select_set(False)
bpy.ops.object.delete()
print("Removed all objects with 0 vertices and 0 faces.")
This will remove every object with 0 vertices an 0 faces.
If you don’t know how to run a script in Blender, you could use google to find information about that.
What is “Untitled”, it could be the texture resolution or that you are trying to export a mesh with a texture instead of exporting the texture separately
