I am trying to produce a flyover of a large area using SRTM data for terrain modelling and geo referenced satellite images for colour textures.
As the area is quite large I think the way to achive this is using multiple terrain objects. I cannot seem to find a way to produce seamless transitions between each of the terrains.
When rendered there is always a visible edge ( height difference) between the terrains. When i render using the same technique in maya there is no visible edge.
Here is a link to the maya mental ray render. two square nurbs planes side by side. Wide render but I assure you there is no visible seam.

Here is the same data, loaded directly via dem import into vue6.5
Three views of visible seam.

All scaling/ translates same for both terrains
Here is the vue file and the dem data.

I have also tried applying as a Picture in the terrain editor but get the same results. Here are the tif files I tried.

I need to keep the terrains seperate as the colour maps that go onto each are 4k square.
Beginning to think is is not possible
Any help/ideas will be greatly appreciated.
