We did recently switch to Maya and in fact started out using Maya LT 2016 when we subscribed! It’s a great program once you can get used to the Convoluted Maya Workflow, I have no problems using the models that we’ve created in Maya in UE4 now that I have a little more comfort using Maya LT.
I learned using some videos from InfiniteSkills based on Maya 2015 (not Maya LT, just Maya) and Videos on YouTube, although the InfiniteSkills videos helped the best. Maya 2015 and Maya LT 2016 are very similar in Modelling features.
