1. Scene Setup
- Open your Blender scene.
- Delete all default extra nodes.
- Import your character or 3D object:
- Right-click → Import → choose your file.
2. Simulation Domain
- Add a domain node.
- Set domain size according to requirement: 300 x 200 x 50.
- This creates the bounding box for your simulation.
3. Smoke Emitter
- Add Emitter Volume.
- Shape: Box, Height: 0.5.
- Set Emission:
- Fuel emission: No fire, only smoke.
- Density: 200%.
- Check simulation: press R + Space Bar.
4. Adding Force
- Add Force Drag Node → choose Force Line.
- Direction: downward
- Either rotate, transform, or apply a negative value → -200.
- Optional: add repel force.
- Press the Space Bar to check the effect.
5. Keyframing Force
- Go to Force Line → Force Activity.
- Enable/disable at specific frames to control simulation timing.
- Press R + Space Bar to preview animation.
6. Smoke Color
- Go to Shader Editor → Smoke Tab.
- Use Color Ramp → set as Exposed Color Gradient.
- Connect the gradient to the Smoke node.
- Choose the desired color; black smoke is the default in this case.
7. Fire Emitter (From Character)
- Add Emitter Volume for fire.
- Geometry: connect to Character Shape.
- Emission: Fire only, disable smoke.
- Add Force Line if needed for fire movement.
- Press R + Space Bar to preview.
