About this project
What does Validate Scanner add?
Validate Scanner
Validate Scanner adds a Scanner that highlights placement errors in Mekanism multiblocks, making it easier to find and fix blocks preventing a structure from forming correctly.
Validate Scanner

Description
When a Mekanism multiblock structure fails to form, it can sometimes be difficult to determine which block is causing the problem.
The Validate Scanner helps by highlighting the detected error position directly in the world.
Instead of searching through the entire structure manually, you can quickly locate the problem block, fix it, and continue building.
How to Use
- If a Mekanism multiblock structure does not form correctly, right-click with the Validate Scanner.
- When the scanner is turned ON, the problematic block position will be highlighted.
- Fix the highlighted block.
This allows you to fix multiblock structures one error at a time.
