I'm sure a lot of you would know this but for those who don't, CGTrader have a whole bunch of free assets Their search for free assets is a bit painful as they mix in paid assets for obvious reasons. It can be painful to have to search through more models and to get your hopes up only to realise it is a paid asset you liked. A simple tweak for the URL will exclude the paid assets from the results. Here I'm searching for powerups but you can change that to whatever. The price is also in the URL so you can manually set that to 0 for from and to as I have done here and then you get rid of all the paid for assets from the list. https://www.cgtrader.com/3d-models?keywords=powerups&price%5Bfrom%5D=0&price%5Bto%5D=0
