Cyberix3D - Free Online 3D Game Maker

I've found Cyberix and I'm prety sure it has lots of potential. But since i would like make a game in an open world I'm wondering if we can upload terrain maps, and if it can be done how do it and which formats are acepted; or if there is not option and terrain must be made by adding blocks models.
Thanks in advance

You can modify the terrain's Height Map, Normal Map, and Texture by changing these values:



You can search for ready made height maps:
goo.gl/Sjf9XY

Or create your own height map using this tool or any similar tool:

Thanks for your answer, I've done a quick text with the premade terrain and seems it works fine in the way I want. Now i should go into try make custom high maps, not much free time so it will be slow, but i'll try go into it and for ure there will appear more doubts

You can also use this tool to generate the terrain:


And press this button to export your heightmap:

thanks for the tip; I had in mind try another one I used some time ago nemesis.thewavelength.net/index.php?p=8
But i suppose the one you posted works for sure fine with Cyberix
