where can i find free or cheap royalty free 3d models? for example daz3d offers some free models but in fact you must buy $500 developer license. i want a site that has no hidden fees.
of course i use unity asset store 
Personally, I think google is the best if you’re searching for a specific model…
you are right, i can find so many models but i can not clearly decide if they are royalty free. it would big problem legally.
this site says;
By downloading this model for your free non-commercial use you agree to the terms as detailed here
i need for commercial use. paid options are expensive for me
www.turbosquid.com - very reasonable prices and good licensing options. Some variability in quality- so ask turbosquid staff for help.
Usually, if it’s a bigger site, you can find the licensing pretty easily.
They look great
I am still confused when I read some of the results
I had a lot of trouble finding cheap assets for my games too (I’m a programmer). I host a site for cheap very high-quality assets for games called PolyPie here: https://www.polypie.com I hope someone finds it useful!
