Combines 3D manifold solids: union, difference or intersection.
Manifold Operations
Computes a set operation on the manifold solids of its inputs, each brought into world space first, so upstream transforms are honoured. The result is a manifold solid again, so booleans chain. Feed it to geo/M3DTriangulate to get a renderable mesh.
By default it works in pairs: input0[i] with input1[i]. Set mode to "all together" to combine every solid of both inputs into ONE result instead, which is how several solids are subtracted from one. In that mode the second input is optional, so a single Merge of all the solids is a complete graph on its own.
| Name | Type | What it does |
|---|---|---|
| operation | UInt8 UNION · SUBTRACTION · INTERSECTION | Which set operation to compute: union (both solids combined), subtraction (input0 minus input1) or intersection (the part they share). |
| mode | UInt8 INPUT0_TO_INPUT1 · ALL_TOGETHER | How the input objects pair up: 'input0 to input1' computes input0[i] op input1[i] and outputs one solid per pair; 'all together' combines every solid of both inputs into a single result, so a subtraction takes the first solid minus all the others, and the second input becomes optional. |
Scenes you can open in the editor that teach this node.
A manifold boolean keeps no primitive attribute, so a colour set per face is lost when a corner is cut away. A primitive ID does survive the boolean, and geo/AttributeCopy matching by that ID brings the colour back onto every face cut from a coloured one. The walls the cutter made have no source face and keep their own colour.
