Hi Filippo, yes it's possible to do that type of thing automatically with a script, the script can save the previous settings, change them to what you want, take the screenshot, and then restore the saved previous settings.

Check out here for an example of this:
http://moi3d.com/forum/index.php?webtag=MOI&msg=5381.1

I think the one in the first message of that thread does most of what you want already, with saving the previous viewport background, changing the viewport background to white, turning off the grid (there are separate things for the grid and the x/y axes of the grid), then taking the screenshot, then restoring things.

I guess it sounds like the main thing you want to add is the metallic lighting, what settings do you want for that, just the same as checking only the "metallic lighting" checkbox option or any other lighting parameters in addition to that?

The script code for turning on metallic lighting is this: moi.view.metallicLighting = true;

The script code for turning off metallic lighting is this: moi.view.metallicLighting = false;

So you'd just insert the "turn on" part before the screencapture, and insert the turn off part after it.

Does that get you set up?
