One thing to watch out for is what Autodesk did with the initial release of Maya Indie. Originally, only the first year was at the $250/year indie subscription price and that was then set to renew automatically at the full $1620/year subscription price for the second year. Now, Autodesk changed that on August 7th, 2020 so that the renewal price is now at the $265/year level but current users are a still suspicious as they say that the terms of the indie subscription do change often and therefore strongly recommend that everyone shut off the auto-renew option.
Plus, the ability to get the indie subscription is a well kept secret at the Autodesk site and you are more than likely to be directed to Maya Light which is NOT the indie subscription. Here is the link
So once again, we see that nothing is clean and clear when it comes "to good to be true" licensing. Honestly, this is where modo beats everyone and that may be one of the main reasons why their users are so passionate about the software as they have a very simple and fair model: upgrade from any past version for the same price under their maintenance plan of $440.
Honestly, if MAXON allowed perpetual license holders to upgrade to any future perpetual license version for the same price, I would not need an indie version. That would be ideal.
