This resource pack repaints all lunecast and blackplate blocks from the Portal Mod so your custom puzzle rooms match the industrial aesthetic of the first game rather than newer chamber styles.
Structuring Walls and Floors
When laying out a test room, combine the two main structural block families to show players where portals belong and how the room is framed:
- Lunecast Blocks: Place these dark grey industrial panels on surfaces meant to stand out as clean test surfaces or bright structural walls.
- Blackplate Blocks: Use the dark metallic blackplate blocks for non-portal framing, recessed walls, staircases, and tiled floors. Mixing recessed blackplate structures against flat lunecast walls recreates the classic layered panel look.
Adding Age with Mossy Variants
Not every chamber has to look newly maintained. The resource pack also restyles the overgrown mossy variants of the blackplate blocks.
1. Build the main shell of your chamber or corridor using standard dark metallic blackplate and lunecast panels.
2. Swap out patches of standard blackplate near corners, broken ceilings, or floor edges with the overgrown mossy blackplate variants.
3. Pair these worn patches with exposed staircases or recessed floor pits to give older puzzle rooms an abandoned, overgrown atmosphere while keeping a consistent dark industrial palette.
