How to start Gaea

gaea start menu

This is a start menu of Gaea.

I would recommend using Create a terrain(Graph).

You can also sclupt your terrain with Sculpt in Erosion Studio.

It will require a height map so it’s better to create a terrain first then export a height map to work in Erosion Studio.

Thoughts

Gaea has a great UI/UX design and very easy to work with.

Although it has a bit of bugs here and there, I was able to output everything no problem.
I’m really excited to see how Gaea would develop with bunch of cool features coming up.

Also, if you purchase Professional or Enterprise license, you will be able to use automation features and bridges to third party applications.
