MayaLT is a perfect tool for indie gamedev, there’s not noticeable difference between MayaLT and Maya if your goal is modeling, rigging and animation. MayaLT has complete modeling part and there are minor limitations in rigging / animation parts, but you can live with that without any problems. As far as i know there’s not polycount restriction (especially if UE4 is installed on your machine) and you can communicate with other apps through FBX. MayaLT doesnt support plugins in general, but MayaLT 2016 Extension 2 supports Nvidia PhysX plugin (i.e. cloth for UE4). Do you need dynamics and particles?! Welcome to Houdini
