Are there any addons to get the REAL vertex count? e.g. if I have flat shading (which is default in blender tho) I will get way more vertices then blender shows on top of the window, and if I have UV seams it will increase even more.

I've found some scripts (not plugins) that count UV vertices, but it's not what I need. I don't know the api of the blender, so I can't write the addon myself in one day, and I have no time to learn.

    $\begingroup$ I'm not sure what you are asking as the shading type doesn't effect the amount of vertices. Are you at some point getting more vertices than blender is reporting? $\endgroup$ – Ray Mairlot Aug 11 '16 at 13:04
  • $\begingroup$ i'm modeling for unity. and now i'm learning to model objects that have less then 300 verts (for batching in unity), but when blender shows exactly 300 verts, unity shows more then 1600 (if i import normals from blender). but is i recalculate them to be smoothed (or choose smooth shading in blender), i will get 300 verts like is shown in blender. $\endgroup$ – curly brace Aug 11 '16 at 13:11
  • $\begingroup$ but this is without the uv. if i create seams, i will add some more (not very much) verts to this counter, which blender does not count either $\endgroup$ – curly brace Aug 11 '16 at 13:11
  • $\begingroup$ UV seams increase your polycount? $\endgroup$ – Bert VdB Aug 11 '16 at 13:21

    $\begingroup$ This is really more of an issue with exporting to Unity or within Unity itself, rather than Blender. $\endgroup$ – PGmath Aug 11 '16 at 15:33

Use Edge Split

Do not use hard shading, always use smooth shading on the whole object and use the edge split modifier instead. You can split edges based on angle or mark edges sharp with ctrl + e and mark sharp manually. This will make blender report the proper vertex count when no seams are present. Using the script that counts the UV vertices should give the proper vertex count with edge split and seams.
