Ok, thank yor for advice. Yeah,I understand it. 8 bit height map is limited to 255 step info, what is not a lot if I want more details, 16 bit would give me 65535 info, what is a bigger span for height map. I have to find high resolution map source with at least 16 bit data. I thought if I converted 8 bit map into 16 in Photoshop, Photoshop would automatically fill in the gaps between pixel values, some average value between pixels and would give more data to my dem map, made surface more smooth. But I can achive same thing by adding turbosmooth or decay, blur in displacement modifier.

Hi! I managed to solve problem 1 - selected edge polygons and then deselected smoothing groups, that solved it. I use .png height maps. The source sites are: Opentopography and USGS explorer. Both sites give source files, that are in 8 bit. I use high resolution maps. If I convert 8 bit source displacement map to 32 bit in Photoshop,scale it up, add some blur, will that help? I tested it and it looked the same.

Hi! I am learning to create landscapes from DEM data and satelite images. I use 3ds max. Problem 1: I create plane with 1 miliion polygons, use diplacement modifier, add height map then scale gizmo a bit to correct edge distortions. Then I select edges of the plane and move them down and make them planar along z axis. The result is looking bad as seen at next image, ugly lines, it should render normally, what can i do? https://ibb.co/jNLmB6 Problem 2: Plane has 1 million polygons and the height map is 8k pixel. How could i rid of the steps as seen in the following image? Should height map be higher resolution to eliminate distortions? https://ibb.co/f1XcJm Thank you !
