Substance 3D Painter on Steam

[David BK]

I just purchased Substance 3D Painter 2022 on Steam and I have a few questions.

1. I am confused about the expiration date of the free updates. Will I no longer be able to receive free updates at the end of 2022? Or after one year from the date of purchase?
2. After free updates expire, will I still be able to run / use the software without limitation?
3. What is the cost of updates after the free updates expire?

Thank you!
