I made a height map based on a displacement, with a very high vertex count. However, some parts of the map are flat because the terrain actually... is flat. I have now 1 million vertices, of which at least 80% are quite useless.
So: I would like to mass-dissolve vertices that are: - adjacent to each other - same height ...so that the flat parts of the terrain would become simplified, to reduce unnecessary vertices (and thus file size and CPU effort etc)
I do want to keep the steep hills and canyons with a lot of detail of course, as you can see on the lower half of the image. It's just the flat parts I want simplified.
Is there a way to do this without doing it manually? Because that would take ages.
PS: I tried "limited dissolve" but that kills the app.
Thanks in advance.
