So after getting the help of a very talented programmer friend of mine , we are almost ready to submit a mesh to terrain converter plugin. What it does at this point is take any mesh and attempts to convert it into a terrain object.
It currently supports fbx and obj as an input and a variety of sizes.
You can import a terrain no matter how high/low poly and it will try it’s best to convert it to the best terrain for the specified size.
If you have any other questions and feedback post them here and maybe we can address them before we submit.
