I created a texture with transparent parts for the block model, but the transparent parts of the texture were rendered black.

How can I render those parts transparent?

You need to add this field to the model json file of your block

"render_type": "minecraft:cutout"

or

"render_type": "minecraft:translucent"

depending on if if those parts are semi-transparent or fully transparent.
