DeltaFX is a website that provides digital 3d assets (PBR Materials, Models, etc.) under the cc0 (public domain) license. This repo contains source code for the website.
The website is built using plain HTML/CSS/JS/PHP. You can run it on a live server, but if you want downloading to work, then you need to host a server for php. I recommend using this php server vscode extension: https://marketplace.visualstudio.com/items?itemName=brapifra.phpserver
