Does anyone know of a conversion of these for sims3 or something similar? http://modthesims.info/d/316083/ath...fields-set.html

I saw these by Severinka @ TSR https://thesimsresource.com/artists...set/id/1128770/ but they seem to be indoor sets. TSR also had a tennis set I think. You could probably create an outdoor field using terrain paint and recoloring of floor tiles . Cloudwalkersims had bleacher from a horse show set you can get via wayback machine https://web.archive.org/web/2016051...-community-lot/ . Cloudwalkersims also had a baseball bat acessory and links to poses also via wayback machine.

someone redid the one from Sunlit Tides which is what I would suggest.

and then with the jogging marker you can make the track work

I use these - https://www.thesimsresource.com/dow...ourt/id/994547/ - to make my own sports field. Plus the bleachers mentioned above.

I wanted a small baseball field for my little town and used the stadium rabbit hole rug as the pitcher's mound. And in my other town I made a small soccer field next to the school and placed the stadium rug inside.
It's nothing fancy but it's cuter then the huge, kind of ugly stadium rabbit hole.

Thanks all, but I was looking for the objects not a lot. I wanted something I could add quickly behind schools or to parks. I do already have the indoor sports courts by Severinka, but yes that was closer to what I want.

Around the Sims 3 has some floor markings but they look a bit out of control - https://aroundthesims3.com/objects/..._sport_03.shtml
