Thanks for the detailed response. I will be revisiting this soon and will employ your suggested method.

In the meantime, I wonder if this couldn't be an option in the height field convert node?

I am not sure the best way to do this… scale using the heightfield file node's uniforum scale parameter or a transform node? Also, when you say voxel spacing do mean scale up by a world space size of a voxel? ex. 1024x1024 disp map, with a size of 100 (size method = size of largest axis) a single voxel is ~0.0977 units in world space. scale up by that much then?

Some what related, but how about a tile split has voxel padding option built. Would it make sense to build in a voxel pad when loading heightfield files from other programs?

Thanks for your help!

So shared points on the grid blend samples from at most 4 voxels? In the case of an interior grid point that is.

For me I ended up redoing all the work I had done previously in Houdini's terrain tools because I couldn't work out the way to get the one tile I wanted to do in Houdini to line up with the other tiles done in other programs. BUT even within a pure Houdini terrain workflow, I am still struggling to have a cropped section being up res'd and still lining up with neighboring pieces. For now I am just exporting the high res Houdini terrain as a displacement map and using that to displace a mesh which was generated from converting the whole terrain to a mesh, cutting out the piece I need, and making new uvs for it.
