Thanks so much @OSUblake and @ZachSaucier. We'll give lottie a try for our rendering engine, as it seems pretty well supported. As @Saurabh Nandwana mentioned, one of the big issues we've run across is the large number of moving objects in popular cartoons like the Simpsons that we've tried to vectorize. Either way, I understand this thread is a bit off-topic for the forum, so maybe we can leave it here for now, and follow-up via DM. Thanks again!
