I’ve made an elevation map based off of a perlin noise map.

I then made a simple terrain texture based off the perlin noise map.

I then created an Elevation mesh and used the texture generated.

The problem I’m facing is that the texture does not map onto the elevation map the way I expected.  It’s slightly off-set and looks ugly.

Here is an illustration of the problem:

I want each new elevation to be clearly defined by its colour.  if anyone remembers the game 4D Sports Racing (aka Stunts),  it’s supposed to be kind of like that.

Can anyone provide me some insight or suggestions on how to fix this?

humm not sur to understand you probleme
but elevation use rvb not gray scale
so you can create more map and use BitmapData.threshold
to isolate your layer
