Hi

I am trying to place two, high-res(16384x8192k) UVs on one plane. I get those UVs by dividing one big color photo of terrain i am interested in. When i am adding it on my plane by 2d textures nodes, there is a small problem, because a black stripe shows between them. It cause a problem when i am rendering my terrain height field.
I saw, that problem occurs when i am using mia_material_x. On other material like blinn, uv's looks good.

Photos of my problem:

Any ideas how to fix that? I tried doing it couple of times.
