    Hi - new to Unity3D, and I'm an illustrator with no experience making assets for games, so here we are!

    I'm building a level, and the guy doing our assembly and development advised me to keep the poly-count (tri's, I know - NOT quads) to 20k.

    Now, I don't know how different Unity3D is from other game engines, but I regularly read numbers like 1 or 2 million for levels - I regularly read numbers like 60k for characters.

    Should I REALLY be worried about keeping the poly count to 20k for an entire level? I've gotten it down to 31,486 tri's.

    And help would be GREATLY appreciated!

    Lower the poly count is better it will be for the game. I don't know if you have buildings, but if you do delete all walls, floors and anything else that you can't see.

    Originally this was a purely 2D game - now I'm making this (attached image) into a 3D mesh since they changed it to 3D.

    Did you ask why?
    Is this going to be a mobile game?

    Not for mobile games.

    If this is a mobile app - I'd say the 'guy' is probably being smart. If this isn't a mobile game I don't see going over 20k as being an issue, but you should probably talk with your team about it.

    Unity has a lot of things built in that can allow for higher poly counts - but polycounts aren't the big issue for optimizing a game now-a-days. With real-time lighting and shadowing, reflection, cloth sim, particle fx, post effects processing, etc. etc. All those play a big role in how the game performs. With high resolution fx and lighting it really takes a lot of tweaking to get a game optimized to run on a variety of systems.
    Poly count - really isn't the bottle neck in the system, but no need to waste and create un-needed mesh data when not needed.

    Thanks guy!

    Different flavors of XBox and PS, PC/Mac - and eventually, yes - flavors of mobile (tablets, not specifically phones).

    The more I read about Unity, the more it makes sense with how it pulls textures as well. I just got the level environment down to a smidge over 17k - still got a lot of rocks and boulders to populate it with, but I'm pretty sure it'll be only a little over the 20k suggested limit.

    Yeah, he's gonna have a sunlight with hard shadows, and add some atmospheric FX (wind, a little sand flying through the air) - no cloth though, and I don't think the hair will animate either but be painted onto the characters' meshes.
