flames like fire in fireplace

Unity Engine
1

Hi, I’m new in unity and try to simulate the room with fireplace. Used small and large flames in Standard Assets but it’s not looks like fire. Does anybody has expirience with making realistic flames?

2

look at the unity 3d tutorial, around page 22. They show how to make flames for a jetpack from the particle engine.

HTHs.

edh has a good suggestion, but even so, simulating really good, realistic fire is not really something the Unity is fully capable of in itself. I’d suggest trying a third-party 3D modeling program like Maya or Blender (Blender’s free), etc. You might be able to simulate the fire in there and maybe animate it in Unity or something.

I remember seeing something with flames floating around the forum…

And quick search found it :slight_smile:

Around half way down there is a unitypackage

At the very least its a start.

If I were doing this, I would use photoshop to create a flame and them make a few variations of it by using a distortion filter; save each variation of the flame into a single tiled texture and then use that texture for UV animation on the particle render.

Just keep it simple by using a Unity particle system with textures, I wouldn’t suggest trying to model the flames in 3D.

There are many tutorials on the web explaining how to create flames in photoshop. And there are many explanations on this forum that describe UV animation in a particle effect.

thanks all for reply. Think it’s real good idea use 3thd part system to do it.

Hey guys,

How would one add light emitting to fire particles? I would like to make the fire light the room as well with those flickering lights that fires make.

Thanks a lot!

Wow for their fires use two separate billboarded planes slightly separated with an animation atlas on them. Gives the flames a nice 3d look, that is unless you fly above them.

No real need for a particle system for a fireplace, unless it’s spitting sparks and cinders about.

Thanks Quietus!
Even if there would be no need for particles is there a way to make those particle flames emit light? Its just that I already have those there so thats why I am looking rather in this direction. (and this would be in a small demo).

So basically what I wanted to know if there is a feature like this in the particle system, or I need to put a point light in the fireplace and make it flicker and change randomly intensity by script.

If you look at this demo:
http://www.pixero.com/white

there is a fireplace with particles and emitted light is synchronized with the particles coming out. So that what I wanted to achieve.

Thanks

If a realistic light to go with the fire is what you want, then just use a light and animate the cookie. You could drive both sets easily with the fancy animation editor. It would look far better than a particle version.

Of course that hinges on actually having a good artist. Yeah you can generate some ‘flames’ easily in photoshop. But to get the color and the feel right, you need that queer eye for the straight guy sort of instincts.

Thanks for the replies.
About the light animation I’ve found my happiness on the unity wiki where is a script for the “flickering light” effect.

Thanks
Greg

Great particle system, looks really nice. I’m using it in a research project that works with the MS Kinect.
