How to make something like this in photopea?

I have no idea what I’m doing when it come to UI design, but I want to get into it.

How would I make something like this in photopea?

Not the full white bar the loading bar.

How would I make it look like some parts are missing, or look like it’s been cut off in some parts. How can I do this?

You can simple use a grudge map and cut it off.

I get my grudge maps for Texture Labs as there’s a ton of free grunge images, then go to the Grungy Masks tab on the left.

Steps

  1. Import the image and make sure it covers the whole desired element, Do not stretch the texture without aspect ratio, it makes it look ugly and unrealistic.
  2. Rasterize your element.
  3. Go to the select tab while selecting the grunge texture, and select color range, and change the mode to shadows.
  4. Click back on your element and click delete on it.
  5. Use Control D to unselect and delete the grunge.

If you want it to only go on the edges, you can copy the same object before the process then use a gradient texture from its original color to a transparent color.
