In the above image, I have a main map which seperates the forest from the river area and trails. The nest map is use
seperate the trails from the river area. Every things works find with just the main map. The problems seem to happen once I started working with the nested map. I have rule out ecosystems and textures, by changing it to only seperation of colors.

The wierd problem is that I must scale the iamge by 341.3 ( I believe that is the value - I calculated it by 1024 / 3 ). and also offset. I could not perfectly get the offset to work because it will not let me go more than 100 in any direction.

I can probably work around with some of these because its not perfect.. But I am working a technique to make trails easy on terrains and I really would like this work.

You're using Vue 5 Infinite right? What mapping mode are you using for the textures? If you use object-parametric mapping, then you don't have to scale the picture. It will fit on the terrain without tiling, no matter what the size of the terrain.

Thanks.. that is definely related to it.. I am curious what are rules about using nested materials.. I move everything to Object Parametric and my trees disappear in ecosystem. I think I got it now, my scale was off on one my main materials also. Thanks..
