script to Query for number of reversed and Overlapping UVs

[RichSuchy]

Is there a queryable command that returns the number of overlapping and reversed UV's an object has. I want to write a check in script that parses a selection of models and prints a report about the selected models. Found two python scripts online but neither have propper syntax and don't do what I am looking to do.. The UV editor hud shows this information in the lower right corner so it seems it would be simple. Looking through the mel commands I came up dry.

For backfacing select your object in object mode

SelectUVMask;
SelectUVBackFacingComponents;

For overlapping

SelectFacetMask;
selectUVOverlappingComponents 1 0;

Thank you so much!

I tried to create a quick test of the Backfacing UV counter.

I might be missing something simple here but is there a reason this would not work. My array appears empty even though I purposely created bad UVs. The bad UVs are displayed after the command but not captured in my array.

SelectUVMask;
string $backFaceing[];
$backFaceing = `SelectUVBackFacingComponents`;
$strSize=size($backFaceing);
print $strSize;
clear $backFaceing;

$strSize returns 0

It looks like defining the selection can't be done at the same time as creating the variable, you can do it like this to get the result you're after.

SelectUVMask;
SelectUVBackFacingComponents;
string $backFaceing[] = `ls -sl -fl`;
$strSize = size($backFaceing);
print $strSize;
clear $backFaceing;

I wish these commands had some documentation. Thanks a bunch, That is indeed a solution (slapping forehead for missing the obvious)

Yeah it would be nice if the mel reference had been updated in the last 10 years, it seems really out of date.
