I'm in the process of figuring out blender (on what could be considered my 3rd project I guess), and while browsing tutorials and youtube videos about blender, I've come across the topic of PBR materials, and have found it intriguing. I've found that using these materials makes my renders look a whole lot better than if I just slap a flat texture on the objects, but I'm a student and don't want to be spending money on this hobby just yet, which has run me into the issue that there aren't a whole lot of these materials out there that aren't reserved for some payed service. Do any of you know of any material libraries out there with PBR materials for free? So far I've been using the free materials on poliigon, and came across freepbr.com, but I can't figure out how to download any of the textures/maps from the latter of those two.
Any help is appreciated! Thanks, Ethan
