Realistic terrain

Hello,
How can I make a realistic terrain for a game free?
I’m new to Unreal Engine 4.

I speak english and spanish.

From what I can gather, World Machine offers a free basic version that’ll allow you to export 513x513 heightmaps for use in the engine provided that you don’t use it for commercial situations. Otherwise just generate a terrain in unreal and get sculpting with a mouse.

You can also try TerreSculptor. Which can be found here Page Redirection

The beta is free to use for the time being (till August 1, 2016)
