Some performance questions about polycount

Oh okay, thanks.

Why not make some different meshes each with a couple of hundreds of lamps

Yes i thought about to making it this way. Iam not a pro in ue4 and need much to learn xD
Well i was not sure how to realize 30k of mini lamp meshes with material animations , you know like blinking or flashing… with UV animations or blueprint, i also dont know, whats faster. My idea was to create lamp groups with differrent material instances and using BP to animate the material emissive channel for the blinking/flashing effect. So before ill think about thousands of meshes, thats why i wrote here.

I actually dont know what do you mean with instancing for the lamp meshes?

Btw i need 30-40k of this small lamps:
