About this Mod

A simple mod, that adds various blocks from Portal games!
Good-to-know:

You can use it in your custom modpack.
Im not a professional, so there are 2 plus blocks: double_white_panel_1_bottom and top, these two has to be placed on each other to create a double wall, where the textures are connected. (sorry for that, I couldn't make the connected textures work...) If you know how can I get this to work, please text me on Discord: b4h4m4k.
Have fun!

Frequently Asked Questions

Portal Blocks server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Portal Blocks compatible with forge?

Portal Blocks officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Portal Blocks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Portal Blocks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
