Hey everyone!

Ignis 2.0 is here with absolutely free DLC included! DLC includes 5 new Fire VFX styles to fit the flames perfectly in your game.

New VFX Styles:

  • Wild - Improved default fire style.
  • Gentle - Perfect for calm setting of fire.
  • Simple - More traditional campfire looking variant.
  • Old School - Billboard flame for all you nostalgia lovers.
  • Only Smoke - Smoke that is coloured from it’s root. Use this for maximum performance solution for humongous fires seen from far away.

Impressive, does it work on skinned mesh?

And is there billboard fire option instead?

3

Yes it works on skinned mesh, although it requires some manual work to tell the places where you want the fires on your mesh to be (You need to add triggers/colliders to the bones). But after that the shader works beatifully and the flames leave trails and move when your animation plays.

And there is no billboard option for the fire, but I will do optimization in the future for VFX graph. I suppose that billboards would not look too great with this system since it’s all about shapes of the objects. So I will probably create some LOD-style alternative slider when player is farther away.

I see there are some semi transparent particle. What about sorting order. How it will work with other transparent object in scene ?

5

I don’t see a reason it would not work. Are you concerned about the flames popping in front or not showing due to the transparency? Just tested with transparent object and flames displayed correctly whether they were in the front or in the back of the transparent object.

Hello everyone,

I planned the next update and version 1.2 will include:

  • Wind will affect the flame (TVE Motion and Unity Wind zone)
  • Particles can extinguish fire (So you can add your water/smoke/anything to put out fires)
  • Trigger events with delay from ignition (e.g. explode a barrel after it has burned for 5 seconds)
  • Ignition time (In real life usually it takes a while for some materials to catch fire, so user can customize this time)

The version 1.2 update will be released next week so stay tuned!

Stay safe and keep creating,

A small sneak peek of the version 1.2 update called Wind and Firefighting:

In the video you can see the fire extinguished by raycast, but it will be also possible to do this by using Unity Particles!

What do you think?

  • Extinguish/Ignite fire with particles or raycast
  • Wind interaction
  • Trigger events from burning a certain amount of time e.g. explosion

Hi, I have a problem when putting out a fire with particles. I believed I followed the instructions accurately, and it basically does work, however, there appears some kind of flame halo around the burning object which expands further the smaller the flame itself becomes. You can see a screenshot here: https://ibb.co/zSxbPGY
I use Standard RP (as HD doesn’t work for me so far) und 2020.2.1
The other thing, which is a minor one, is that attached lights are not turned off when a fire dies by itself.
