Hey Michael,
Im working on a fairly large model for a real time engine, I use MoI for the modelling
(I miss instances or components like Sketchup and groups, but its OK, MoI workflow is so smooth I forget them hehe)
I try to avoid Overlapping faces, because the scene must be the lowest poly ammount possible

Firs I model with solids to be able to do booleans, I don't care about polycount at this stage
Then I remove all un-necessary faces (its an old industrial factory, reconverted as a modern office, we will never see the exterior anyway, so I remove all exterior faces by hand)
I also remove all the stuff that we don't gonna see...

The model is well optimized currently, but I would like to check if I don't missed overlapping faces (that can cause z-fighting)

Is it possible to have a script that select all surfaces that overlap themselves ? Even if they only overlap by 1%

For example two planar rectangles of 10cm by 1cm, sharing 1cm square

It would be usefull :)

Hi DesuDeus, unfortunately that would be quite difficult to script that - especially for just any surface it would require the script to do some fairly extensive analysis of how 2 surfaces interact.

Scripts are usually easier to produce when they are automating some process that there is already a command for, like just automating what would be some clicks in the UI. That's not really the situation that you are describing here.

Ok, that's fine
Its just a little bit laborious to search for all of them manually
But, its just for optimization so its OK

Even without removing the faces It would run on medium hardware
Thanks for your *always* fast replies :)
