It can be difficult to see which voxel is selected in the assembler. While the system picks the voxel under the mouse pointer with precision, this isn’t always obvious.

Selection highlight: Add a shader to show the voxel about to be selected, reducing guesswork and improving clarity.

Placement highlight: Apply the same shader to the building floor or target voxel once a module is selected, making placement clearer and reducing errors.

These changes would make the assembler more transparent and responsive, following a similar behaviour to the stamper visually indicator.
