precision in export dialogue box
« on: June 17, 2020, 10:30:36 PM »
How does the precision work in the export dialogue box? what's the scale? what's better vs worse (lower number vs higher number?), couldn't find it in the documentation. Does it act on the texture only?

It's the number of decimal places used to store the coordinates of model vertices.

I sometimes use it to reduce file size if i don't need 6 decimal places, i.e. if my project units are meters, and the polygon size is in the order of centimeters, then i may not need sub-millimeter precision so could turn it down to 3.

Conversely if you're working on a geographic scale, with degrees lat and long instead of local coordinates, then 6 decimal places might only give you centimeter level precision and you may have to increase it depending on your application.
