No change at all. A plain, constant texture loaded on import. |

I just looked at it...the object is 337 triangles, not 180. Whatever your 3D app says doesn't count; only the number in Unity matters.

[smacks head] Right. When I was looking for vert counts earlier, I looked in the right place, but this last time I didn't 
That should be it then... |

Yep, remove another 37 tris and it will batch. Actually the wording in the docs is a pretty confusing "bug" and should be fixed...if someone else hasn't reported it, I will.

So it's tris, not verts ? 
Anyway, all of my objects are less than 100 tris. |

It actually bug in the code, not in the docs. It _should_ be verts. Will be fixed in the next release.  |

That's a bit unexpected, but actually good, since 300 verts is obviously less restrictive than 300 tris.  Or is there still a tri limit too?

Can we expect this "bug" to be hot fixed?
So that we can actually use 300 verts instead of tris? It would be nice to fix that kind of thing as quickly as possible so we dont waste our time modelling 300 tri models. |

I have models of 200 vets.
They are not batching.
Similar models with 109 verts, sharing the same texture, batch. |

i will add here even more info:
I have an asteroid, 109 verts. batching
I get this asteroid, 109 verts and edit it in max to make a different shame, more ramdom, adding nothing: unity gets a 200 verts mesh now, not batching again.
I am stuck to this single asteroid that seems to batch lol |

You cant look at the vert count. Unity currently batches meshes of <300 triangles not verts.
Still no reply on when we might see it changed to verts??? |

Same problem here.
40 objects sharing the same texture, leading to 15 drawcalls.
Every object is < 300 verts (yes, not tris, verts, so verts counter is even lower than 300).
Can't understand why.

as fas as I know, in 3d world a triangle is made of 3 verts.
So in a mesh, 300 verts always less than 300 triangles, lot less.
So I don't get the point of your comment  sorry |
