FIRE GEN — QUICK START

Blender 5.2 or newer

1. INSTALL

Open Edit > Preferences > Get Extensions > menu > Install from Disk.

Select the Fire Gen Extension ZIP without extracting it, then enable it.

Disable any older legacy Fire Gen copy first. The Fire Gen Asset Library

registers automatically.

2. CREATE YOUR FIRST FIRE

Select a mesh or curve in Object Mode. Choose Object > Fire Gen >

Add Fire Gen to Selected. The selected object becomes the emitter.

Adjust the effect in its Geometry Nodes modifier; no N-panel is needed.

For a ready-made look, apply a preset from Asset Browser > Fire Gen.

Use Master Clean as the starting point for your own effects.

3. SHAPE THE EFFECT

Choose Flat, Ribbon or VDB in the modifier's setup controls.

Adjust flame size, amount, color and animation. Enable Smoke, Sparks,

Wind or Heat Haze as needed. Some controls apply only to certain modes.

VDB includes Small, Medium and Large fire sequences.

Sparks > Temperature (K) controls both Round and Trail spark colors.

Use Rendered viewport shading to preview the materials and emission.

4. CONTROL WHERE FIRE SPREADS

Use Growth to control the starting point and spread speed. Enable the

weight mask to restrict the effect to a painted vertex group; the default

group name is Group. Object Mask is inside Growth; use its object field

and Invert option to control where fire is allowed.

5. ADD CHARRING

Enable Charring and choose Wood, Iron, Fabric or Organic. Your original

material remains visible outside the burnt area. Use mask/growth sync

to follow the fire, Delay to postpone charring and Memory to retain it.

Organic has three layer controls; Burn Through controls progression time.

6. ANIMATE AND RENDER

For animated characters, place Fire Gen after Armature/deformation

modifiers and keep mesh topology stable. Play from the scene start when

changing simulations. Bake simulation data before rendering arbitrary

frames. EEVEE supports interactive previews; Cycles supports rendering.

Performance depends on the scene, settings and hardware.

7. SAVE AND EXPLORE

Object > Fire Gen > Save Fire Gen Preset saves reusable modifier settings,

not the source object or simulation cache. Open My Presets Folder locates

your saved files. Open Examples Folder locates Examples.blend with complete

editable objects; open that file separately to explore the examples.

REMOVAL

Preferences > Add-ons > Fire Gen > Uninstall Fire Gen removes the extension.

Your scenes, external VDB library and personal presets are kept. The Asset

Library entry is also retained so existing assets remain accessible.
