STL shader open behavior

Hi there! I have an issue and I can’t solve it. So I work with STL files a lot. The problem is when I open a new rhino file and than import an STL file, the rendered viewport looks nice and like I managed it. So the shader is good. But! When I open an STL file with just double click on file - the rendered viewport looks terrible and the shader is bad and ofc the viewport properties are different. Can someone tell me how to make SLT file opens with my managed viewport properties by default?

double cliked STL shader:

Imported STL shader:

import strips the render mesh and creates it new from scratch based on the file that is already open.

double click calls the open command and that uses the render mesh that comes with the file.

In version 8, you can reset this by clicking here:

Thank you! It helped. I opened the STL file, than use your guide and it works. But the question is how to make rhino use this render settings by default? Because I saved file and after it, I tryed to open the same STL file again and it shows the previous “bad” render settings

open it, reset to defaults then type clearallmeshes (this just clears render meshes)

then go back to rendered mode and save it as a .3dm

it should behave.
