How to Build a Pure Crying Obsidian Nether Portal
Assembling the Frame
In vanilla gameplay, crying obsidian cannot be used to construct a functional Nether portal. With the Crying Portals mod installed, you can build an entire portal frame using exclusively crying obsidian blocks.
1. Collect your crying obsidian blocks.
2. Lay out the frame following standard Nether portal size requirements. The minimum functional size requires a 2-block wide by 3-block high opening, forming a 4-block wide by 5-block high outer rectangle.
3. Place crying obsidian along the base, vertical sides, and top lintel.
4. Just like with standard vanilla frames, the four outer corner blocks are optional; you can leave them empty or fill them with crying obsidian or decorative blocks.
Activating the Portal
Once the crying obsidian rectangle is complete, you ignite it exactly like a standard portal:
1. Equip a standard ignition tool, such as flint and steel or a fire charge.
2. Use the item on the top face of one of the bottom crying obsidian blocks inside the frame.
3. The interior space will immediately fill with purple portal blocks, producing a fully functional Nether portal with glowing weeping textures.
