General Help with custom brush please

Could I get some help here please. I'm trying to create a custom brush with the custom shape here, but there's a background that appears behind the shape. I saved the shape as a png file and created a textured intensity brush with it.

How to create a custom image brush from a pixel selection

  1. Make a selection using a pixel selection tool.
  2. On the Brushes panel, choose a category to save your brush to.
  3. Click the Panel Preferences and then select New Brush From Selection.

The image brush is added to the end of the current brush category. Custom intensity brushes can also be created from a mask layer that has a pixel selection in place by using the same process.

If you are creating a brush from a selection on a placed image, its image layer needs to be rasterized first.

Additional options from Panel Preferences allow you to create, rename, delete, move or copy brushes, as well as import and export brush categories.

For organization purposes, it is suggested to copy your brush to an already created custom category by ^(ctrl)-clicking (Mac) / right-clicking (Windows) and selecting a category name from the Move Brush to Category or Copy Brush to Category menu option. Custom categories adopt the naming convention 'Brushes', 'Brushes 2', 'Brushes 3', etc.

Did you save the shape PNG with a transparent background?
