How to Use it ?

1 - Download Houdini [www.sidefx.com]
2 - Don't forget to check unreal on the install process [support.borndigital.co.jp]

3 - Import the hda in Unreal
4 - Drag n Drop the hda in the scene
5 - You should see the hda cooking

Parameters

Once you finished importing all the stuffs ( see quick tutorial in the next post ) you can start changing parameters.

- Try changing the offset parameter, it will offset the noise and basically you get a new terrain



Result



Once you happy with the terrain try changing the resolution to 127, 253, 505, 1009, 2017, 4033, 8129 ( currently there is a bug and the terrain is locked to 1009 )

Tips

- Disable this if you don't wan't to auto-cook each time you change a parameter, you will have to manually recook the asset ( select the terrain, right click, recook )
