Seams between SceneCapture2D components

I have 22 scene capture 2d components used for my 180 degree FOV orthographic camera.

I have 22 materials representing each scene capture, and 22 flat plane static meshes.

Each material is applied to their corresponding flat plane static mesh.

The flat plane static meshes are placed side by side perfectly.

The problem I have is that there are seams between some of the flat plane static meshes (picture shown below).

I’m thinking it’s a problem with floating point numbers?

Any help is much appreciated.
