From Moi to Nvil and back how to stay accurate

There is a setting need to be noticed, View > Scene Scale. It affects the size of the floor grid. The default value is 1. In your case, you can set it to 0.1 so you can use 1on1 scale on import/export.

Do you have a link to the script you are using ?

Here is some links and info...https://moi3d.com/forum/lmessages.php?webtag=MOI&msg=10945.1

Hopefully I got this now....there seems to be an issue with the import obj which changes the size.
so this is fixed now...but when importing it was 100x smaller so I changed the export scale in Nvil and now it seems spot on...going to test some more tomorrow.

tnx.

Ok, sounds like you've sorted it out.

One more question...does Nvil include Matcaps or should I just download them somewhere?

Tnx!

You need to google and download matcaps.
