CreateFluidMask

Example

JSON Example

{
  "class_type": "CreateFluidMask",
  "inputs": {
    "invert": false,
    "frames": 1,
    "width": 256,
    "height": 256,
    "inflow_count": 3,
    "inflow_velocity": 1,
    "inflow_radius": 8,
    "inflow_padding": 50,
    "inflow_duration": 60
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
invert	BOOLEAN	required	-	false
frames	INT	required	min: 1, max: 4096, step: 1	1
width	INT	required	min: 16, max: 4096, step: 1	256
height	INT	required	min: 16, max: 4096, step: 1	256
inflow_count	INT	required	min: 0, max: 255, step: 1	3
inflow_velocity	INT	required	min: 0, max: 255, step: 1	1
inflow_radius	INT	required	min: 0, max: 255, step: 1	8
inflow_padding	INT	required	min: 0, max: 255, step: 1	50
inflow_duration	INT	required	min: 0, max: 255, step: 1	60

Outputs

Index	Name	Type	Is List	Connection Reference
0	IMAGE	IMAGE	No	["{node_id}", 0]
1	MASK	MASK	No	["{node_id}", 1]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this CreateFluidMask node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• IMAGE (IMAGE): ["5", 0]
• MASK (MASK): ["5", 1]
