Hairs in multiplayers games

Hello, i am working on a multiplayer shooter game like battlefield, call of duty, ghost recon, etc… and i have worries about the hairs for my models. It should be arround 10-12 players per map, mostly small to medium size map (close quarters maps but if possible with lot of details).

I have made some researchs but i am still lost. Most multiplayers shooters do not propose hairstyles except few exceptions like Destiny, gears of war… but i cant get a model to see how they made it. I read that Destiny devs developped their own technologies for their “hair salon”. Anyway…

the methods i found so far :

  • there is the “polygons” method but it doesnt look so realistic (like in mmorpgs)
  • there is the “planes” method often used to make great hairstyles (in most solo games)
  • there is the “fur and hair” method but i dont have enough materials to figure out if its expensive in ressources or not, but i guess it does.

so far i have sticked with the planes method but i am worried about the impact on the game ressources. i am planning a character with 15 000 polygons, that you add arround 5 000 for the hairs and 5000 for the weapon. Total 25 000.

I read on numerous forums that characters are usualy arround 30 000 polygons minimal for games… (even a teacher in 3D think so)… but the models i downloaded to get an idea are not more than 20 000 polygons… most of the time arround 12 000. But i did not get any models from the recent games (Next Gen) to say if its still like that or not.

The problem is not really the numbers of polygons, but if i stick with the planes method, it will add lot of “objects” on my characters, it means more draw calls… with the different maps (normal, specular, …) its a lot i think… am i wrong?

I have exposed my problem, my questions are :

  • should i forget to put hairs in a multiplayers game if i want it realistic (good looking)?
  • what is the best method to make hairs for a multiplayers game?
  • is there an other method?

Yeah, i am worried about the final product… hairs are kinda difficult to make and dont want spend time on it for nothing. But if it can be added, it would be great.

Thanks.

Bench mark on your target minimum spec platform. Its easy enough to build the right amount of GameObjects with the right amount of polygons and run a simulation. Keep increasing polygons and stuff till you find your limit, then work backwards to allocate your polygon ‘budget’ to the various effects.
