How to Upgrade an Existing Nether Portal with Crying Obsidian

Swapping Blocks in an Active Frame

If you already have a functional vanilla Nether portal at your base, you do not need to tear it down completely to add crying obsidian styling.

1. Deactivate your active portal. You can do this by placing and quickly removing a block or bucket of water inside the portal opening, or by mining out one of the frame blocks.

2. Use a diamond or netherite pickaxe to mine away the standard obsidian blocks you wish to replace.

3. Place crying obsidian into the empty frame slots. Because the mod supports any combination of standard and crying obsidian, you can replace as many or as few blocks as you want.

Re-igniting the Portal

After placing your crying obsidian accents:

1. Inspect the entire perimeter of the opening to ensure no gaps remain and that every border block is either regular obsidian or crying obsidian.

2. Use flint and steel on the inside base of the frame to re-ignite the portal.

3. Step through the activated portal to confirm it continues to connect to your existing Nether destination as intended.
