Materials not applying to selected faces and instead applying randomly

[aliza_camacho2020]

Hi there,

I'm not sure if this is an issue with my model or how I'm applying the material, but basically I created a pretty basic model (everything is combined through mesh unions). I'm now applying  materials but for some reason whenever I try to apply the standard surface material I created it doesn't apply to the faces I selected and instead applies random all over the object. It's almost as if some sort of jitter/jumble setting is on but I don't think I clicked anything like that (at least not on purpose). Has anyone seen this behavior before and know if maybe I accidentally turned on a setting or if maybe the way my model was made is causing this jumble?

I tried to reproduce the problem and here the material applied correctly at first but then when I tried to apply a new standard surface material it jumbled again.

Then here when I tried to just apply the existing material to a selection of faces it would start to jumble too, so I'm not quite sure what is happening.

I'm very new to Maya so any help is appreciated! Thank you 🙂

Have you tried to delete the history?

Or export and import the object as obj. That does fix a lot of issues.

Deleting the history worked! I didn't realize with union-ing shapes and adding deformers was complex enough I'd get into having to delete history. Thanks for the advice. Glad I learned this lesson before I got into even more complex things! 🙂
