Hi the link to download Quixel Mixer is broken. Either says the page van not be displayed or it just cycles loading. This is for the Win version. The Mac version link works fine.
the download button on Quixel Mixer - All-in-one texturing & material creation tool seems to work for me.
here’s the direct download link if you want to try that :
