Terrain Height

[MarkusR]

why did the min height not allowed negative values?

can not make a hole in my current level for the new water plane.

Because the terrain heightmap is a gray scale image ranging from 0 (black) to 255 (white). 0 is the lowest height level therefore you cant go in reverse (lower than that). The only thing you can suggest is an initial height setting which would put the ground at 127 (middle height) for instance. This way you can sculpt both up and down from the initial height.

hmm ok, i had expected a heightmap is only used to create the initial mesh.

i think i can export the heightmap image, change it and import it again, then pull the scene up.

I would create a mid-tone (127 gray) bitmap and always import it before starting a new terrain.

hm, i can load this raw file into my graphics app but the raw save file i can not load back into engine...

also seems bmp is not supported at import. because 8bit only.

Been there done that.

On rereading your post, I'm not sure if the above will help you. But do make sure you imported it into your graphics program correctly.

@gamecreator,in photoline it looks good, i made it brighter there but the raw export there is more a camera format.

You may want to give another program a try, like Gimp. Maybe XnView does it too. I'm also happy to convert it for you after work if you want to PM me an image file.

 

One thing you can also check is to make sure the raw file from Leadwerks matches the size of the one from your program. It should be the same exactly.

@gamecreator, thanks for your offer. i wrote a simple converter for level up my map.
