For years, I’ve been using CGTextures.com in combination with photos that I’ve taken to create the starting points for some of my textures. It has been my go-to resource for royalty-free textures. If you’re a 3D artist and haven’t been to the website before, I’m ashamed of you! Go there right now and be prepared to kick yourself for not finding out about it sooner.
Anyways, the way the website works is that each user has their own quota of how many textures they are allowed to download. You must have an account in order to download. However, once you hit your daily quota, you can’t download any more textures unless you upgrade your account to a premium account (a.k.a. paid account) or wait till the next day begins.
I’ve recently been introduced to texturelib.com which is basically another texture library. It hasn’t been around as long as CGTextures so their library isn’t as robust and their website is lacking some functionality. It currently has 6,059 textures you can choose from but doesn’t have search capability. I’m also uncertain as to how often the website is updated since it is lacking a “news” feed. Nonetheless, I’m excited to have another resource to look through.
If you know of any other online texture libraries, databases, or resources, feel free to let me know by leaving a comment!
