I go all over the web looking for textures. Some places are fantastic, and others, well, not so much, but they do have one or two textures I can use. Most have PBR textures, now that Second Life has officially released PBR.
The list will grow as I find more, and/or remember where I got them from.
So here are some of the places I've found that might help you find that perfect texture!
*Subscription - Some free textures are available, but a subscription is needed for more.
** Links to websites with PBR textures
*** HDR Maps only
If you still can't find just the right texture, then there is a texture search engine here:
--Reddit also has a GREAT list that's always growing. You can find the link here:
Please Remember SOMEONE is providing the textures for free, please don't make money off of someone else's hard work.
We'll add new pages as we find them, if you have a place we missed, feel free to drop Kitsune Lassiter a notecard in Second Life.
