Pixels being effected outside of selection range

[joeyhathorne]

Hey guys, I've read several posts on here and Reddit and even have been consulting ChatGPT about this and have tried almost everything that was suggested. I'm working with pixel art in photoshop. All of this was working up until yesterday or the day before just fine. All of the sudden, I have pixels beyond my selection being effected. I am using quick select, all my tools have alias turned off, I'm using both erased and pencil to eraser pixels I don't need. I've reset preferences, cleared my cache, turned off my graphics card incase of weird artifacting, feathering is set to zero, smoothing at 0 and hardness at 100%. I'm not sure how to fix this. It's messing up my work flow. Any suggestions?

I love that you asked ChatGPT about your Photoshop issue.  That's hilarious. 🙂

OK so what zoom ratio are we looking at?  It looked to be highly zoomed in.

Do you see an issure when zoomed to 100%?

Do you have a feather set in the options bar?

You mentioned using Quick Select.  Were you using a fully hard brush preset?  

If I understand what Pixel Art is, then I wonder if a square preset would be best?

We can only change hardness and not the preset with Quick Select, so mabe Quick Mask and the Pencil tool would be a good fit.  You'd be sure of no feathering from the selecting, but would still need to check the Options bar

BTW  best way to find the square presets is to use the search bar
