Elevations bitmap
« on: July 24, 2008, 03:44:01 PM »
I assigned all of my land tiles based on a map I created.
I used the make map function to create an accurate bitmap of the landmasses that I then
used to create my elevation map using black as zero alt and white as max alt.
I then saved this as a grayscale 8 bit bitmap.
I imported the elevation bitmap, and none of my land elevations were changed, yes I saved,
closed, then reopened the editor.

I clicked on the water not zero button and found that 6427 vertices were not at zero. These were
located far to the bottom left of my landmasses, way off the map.

Okay, what did I do wrong?

I would have to see the grayscale to tell you that.

But be sure it's 1024 x 1024 in size.
And be sure it was actually saved as a true grayscale bitmap not grayscale color.
And I hope you used more than 2 grayscale levels (black & white), otherwise you'll have spikes all over the terrain.

Edit:Also remember that if you use the map provided by the terrain editor, you are only seeing the map that would be presented on the clipboard in the game. You are not seeing the entire area available to the terrain editor. So if you created a 64 x 64 mile map in 1024 x 1024 size and used that to create your elevations, the elevations are actually spread out over a 512 x 512 mile area and most likely won't be visible on your terrain. I hope that's clear enough. :)

That's the ticket, thank you, was trying to use a 1024x1024 bitmap for a 128x128 terrain.
Followed the instructions you provided and fixed the problem right up.

Thanks :salute
