I have tried different export sizes, different assets, sequential PNG works fine but, I specifically need .gif for my project and I don't want to add more steps to my workflow. The software seems unstable on my version of mac and doesn't play well with the touch pad, small movements during scrolls are huge in translation. It is unpredictable with intuos as well, if the pen goes out of surface range it will close the pivot set box. These all add up to a poor experience for my development process. I tried to get a refund from steam but, they denied me cause I have 6 hours on the software. I hope to give it a crack in a few years if mac support improves. Is there anyway for me to get a refund directly?
