Exporting image from mesh

[Cramman]

I have imported some detailed .obj models from a 3D photogrammetric model. They are very detailed and look great in CC.
I am trying to extract a wall so I have clipped the walls out leaving me with

The mesh, under it I have a cloud, materials and texture coordinates.

It the past I have sampled the data giving me somehting that I can then rasterize, but these are coming out worse that I already have.

Is the a way to export a raster or just a high res image of the mesh?

Thanks

"Render to file" under Display menu does not get the job?
