trying to match a terrain material with a height map problem

Hi all!

I'm trying to use a height map to create a terrain with a material texture that should be matching exactly, but for some reason the terrain and the material apear to have an offset of 10%, ie: both files are 1024x1024, my terrain size is 1024x1024 but to line up the terrain with the texture I have to put in a y offset of 124. Does anyone have any clue as to why this would be happening?



I figured out this problem actually:The material is flipped on the y axis, so by typing in the negative size value for the splat it worked.
