Do I even need Unity Terrain Tools if I use GAIA Pro 2023

[J.Winn]

I have GAIA 2 and 2021. Really thinking hard about getting GAIA Pro 2023. It looks like an All-In-One, Everything you'll need tool. So Do I even need Unity's Terrain Tools in my project if I have GAIA Pro 2023?

Hi @J.Winn, I would say no, you should have everything you need for terrain creation with Gaia already. Both Gaia and the Terrain Tools package work with the Unity Terrain object, so if you find that you miss a certain tool of the Terrain Tool package you can still install it and use it additionally to Gaia.

Thank you sir for the reply.

Typically I tend to use both, but that's just a preference thing. 
As peter said you don't need to though.
