I appreciate fast response.
I have tried opening files with 3D viewer and Unity.
For 3D viewer I have just double clicked on fbx or obj file, fbx are completely black while obj have silvery look.
For Unity I have dragged and dropped files into project, neither of them displayed textures out of box. I did find solution how to apply textures myself, but process is cumbersome. I intend to use this for cutting project but sadly there is interpolation of vertex or for some other reason it doesn't work, so algorithm fails on this mesh, although awesome textures. Will try to make good use out of them
