Hey all, I am a returning player and these new animated avis are pretty sweet. I have been having issues as it will only allow me to download PNGs or JPEGs. I use Adobe Creative Cloud Express; it allows me to animate my work where I want but if I download it to MP4 which is the only way I can keep the created animation but it can't be used here. Other than its just an avatar and nothing special, If anyone could help me with this issue that would be amazing. Thank you
