Extended Block Shapes for Blockus
This additional module creates a bridge between two popular modifications - Extended Block Shapes and Blockus. After installing it, you get access to extended geometric shapes for all blocks from the Blockus collection.
Important note on block search: Special groups for these items are not provided. To find the new blocks in creative mode, you need to activate the "Add to vanilla groups" option in the Extended Block Shapes mod settings. After that, all additional shapes will be available in the corresponding Blockus sections.
