    In the video above is showing what unity behavior I am receiving.

    The expected behavior for me wouldn't be showing triangles trying to build, it would just allow me to select a bit and raise and lower, etc, instead of a huge chunk at a time.

    Hi there.

    The mesh resolution for the physical units ( size) of terrain is too high for the texture resolution of the height map that drives the terrain data.

    Be sure to plan and balance out your terrain unit sizes and then your height map resolution under texture resolution (on terrain data).

    You would then later have to further optimise this
    Say if you had a 4k height map texture on. 25km2 terrain, this is too little resolution and too high a memory print for a single chunk ( plus will have sparse trees/details)

    You would need to chop up the terrain into smaller pieces that you can load and unload when needed to save memory and performance at runtime.


    Hope that helps some
