WHat i like to see in the heightfield map importer is the option to set the coordinates where the heightfield need to be placed. Now i can only import 1 image. and the others are impossible. Tried it with insert but thats nopt working also the scale is wrong compared to the heightfield importer. With insert you only see a very tiny heightfield if your lucky.
Better would be if you can import large heightfield maps and High Fidelity is later only loading the parts from disk that it needs. so size doesnt matter after import.
This heightfield loader need some improvements to work good with split maps.
Also a heightfiedl X and Z positioner in the heightfield importer would fix the problem sofar is see, you can then just easy import every map and multiply the position by the map size. in my case 1024.
