sIBL - HDRi environments for Max, Maya, C4D & more
While I was looking for good HDRi's for car renderings I've found sIBL and I think it can't be wrong to share that with you guys
It's for free, so give it a shot.

For me (working with 3ds max and Mental Ray) it was just some clicks to get a nice outside rendering done. Ok, BG spherical have just a dimension of 8k x 4k most of the time but in my eyes fairly enuff for a nice shot.

Take a look here to see how it works. Ready to use sIBL collections (all for free) you can find here

Have fun with it!

P.S.: Later I add some more HDRi download sites to the ressources-thread. You never have enough HDRi's if you work with outside/car models
