forgive the nosiness but it does seem that at least some of these were yoinked from places that may or may not be cc0, e.g. images 248 through 256 are also found at https://www.3dsmaxfiles.com/2022/04/free-seamless-wall-textures-pack.html from 2022 (and this isn’t the true source either, e.g. 253 has existed since at least 2014 https://gb.thesims3.com/assetDetail.html?assetId=8312005)
this isn’t intended as an attack against you, it’s just a word of caution for those who care about strict compliance for one reason or another (remember when roblox got threatened over the hurt sound they reportedly got from a royalty-free asset cd?)
still very much a useful grab-bag for those who don’t care as much! copyright is a mess and i’m certainly not defending the state of it, and i myself flip-flop between caring and not caring (my wip game has a bunch of clean cc0 assets and then a random twilight sparkle)
