We usually charge an upgrade fee for our assets once a year.
The exception to this is if you bought our product within 90 days of the launch date of the upgrade, in which case the upgrade will be free.
These upgrades are released in alignment with the major Unity versions they support, e.g. CTS 2019 for Unity 2019, CTS 2020 for Unity 2020 etc.
The upgrade price is based on the effort invested to support and grow the asset. This will usually be around 20% of the retail cost of the asset, but will sometimes more if significant additional work was invested.
All upgrade money is fed back to the team to ensure that we can continue update, grow and support our products and customers.
