Question Importing with a script a raw file on a terrain

I'm trying to import a raw file into Unity on a terrain using a C# script, but I can't find any functionality that does the same as what is done from the Unity interface of the raw import button. Is there something specific that fulfills this function? Or how could I solve this problem by another solution?
I have seen other posts from several years ago and none have helped me to solve it.

Thank you on advance

 

I don't think there is a 1-to-1 map.

I just use

TerrainData.SetHeights()

but the values must be normalized 0.0f -> 1.0f

If you want a functioning example of monkeying around with terrain heights, check this:

Right, I'm also quite certain that they didn't include that functionality in the scripting API. Especially it requires a lot of manual settings which actual format the raw data is in. So in the end it's just about interpreting the raw data the way it actually is. Since raw files just contain raw data without any kind of header or metadata you have to know and specify all those "parameters" yourself. So in the end it's "just" a simple for loop which may swap bytes (depending on endian-ness) and normalizing the samples. Of course you have to know the exact width and height beforehand.

ps: that idea of modifying the terrain to match placed colliders is really quite ingenious. Most people always try to do it the other way round A bit of parameterized smoothing at the edges and you can sell it
