Dear Anthony,
as I am guessing by processing you mean rendering it in “sweet” mode, then again this is just the cause of VRAM which is the memory of your GPU. If you lower your triangles count (simplify) you will be able to see the whole scene as in the pictures you have shown. You can just hit simplify in the reconstruction tab and reduce the polygon count to lets say 20 milion and then unwrap it and use texture reprojection which is again located in the reconstruction tab to bake your diffuse onto this new simplified model and you should be seeing both the whole model in solid and sweet and it should have the same color texture.
