Blender fire testing + .blend files

Aug-10-2012    22 Comments

Blender Burning PlaneNow that Google Summer of Code 2012 is almost over it's time for heavy testing and final improvements of my Blender smoke project.

This week I have been experimenting with different fire simulation and render setups to find out new ways to improve simulation quality. While testing out new code I also prepared three fire scenes for download so you can start playing with fire too without having to do days worth of experiments. :p

Check out the renders here:

Unfortunately there still isn't a single click "Make awesome fire!" button. Setting up realistic scene still takes lots of tweaking for both simulation and render. However simulating fire in general should be now much easier with these GSoC changes.

Burning Plane

This scene is an extreme example of texture controlled emission. A cloud texture with animated z-offset is used to generate additional turbulence to fire. This gives a huge visual improvement over a plane that emits fire evenly across whole surface.

Download: burning_plane.blend

Burning Sphere

The basic idea of this scene is very similar to previous one. However this time texture is tweaked with a color ramp to emit some fire even from darkest areas of the texture.

Download: burning_sphere.blend

Fire Pillar

This is a very basic scene I used to test high fuel/flame emitter. Notice how I have unticked "Absolute Density" checkbox from flow, making it "additive" instead. This way fuel can smoothly increase to very high amounts creating long lasting tall flames.

Download: fire_pillar.blend

Please note that to use these .blend files you need a Blender "soc-2012-fried_chicken" branch build of r49779 or later. All scenes are also quite heavy so it's better bake the cache. :)

Update: My smoke code has now been merged to Blender trunk. So any trunk revision of r51259 or later will do. :)

We already have quick explode, quick fur, quick smoke and quick water. What about well-tuned Quick Fire? It would be awesome.

The link for Burning Sphere is burning_plane.blend

Thank you for all the fantastic work you're doing.

Quick smoke operator already has a "Fire" setting in the operator toolbar. However this kind of "tuned" scenes are too heavy for quick operators.

Thanks, fixed. :)

Thank you SO much for this! just seeing your colour ramp for the flame was super helpful! Dropping to transparent on both sides of the ramp does so much for the realism!

Amazing Work! Can´t believe this is real.

Wow !

Thank You so much - and have a lot of Fun!

Thank you so much. I was doing some fire simulations yesterday and couldn't get anything that looked even close to this. Just downloaded your scenes and am going to see what magic you are using. You're fires look so much more realistic than mine does.

Your work on smoke really rocks! I also like very much the new multi-color smoke.

Will it be possible to mix different colors into one resulting color within the simulation?

Hi MiikaH!
Your work is amazing and now I'm trying to deal with smoke and close camera to it. It looks gradiented after render,
how to get rid of the gradient steps. Is it possible?
Thank you!

How do I get the "soc-2012-fried_chicken" build? What does that even mean! I've been using blender for awhile and have never heard of it. Help!

yo mex, go to the blender page on this site scroll down and you'll find the goggle summer of code (gsoc)fried chicken build. with all the great smoke sym tools. contained in that specific branch of the gsoc.

Hey, people, will soc-2012-fried be merged into the main trunk? It's very useful, but it's not uncomfortable to keep several builds on computer.

i see the new smoke tools have been added to the 2.64a release .thanks for all the great work you developers are doing.

for some reason smoke is turning multi-colored in the viewport only,renders as expected, but not in viewport. if anyone else is noticing this can someone leave a note here.looks really cool though. but just wasted about 3 hours trying to figure out what i was doing wrong. then the next day happened again. just would like to know if its just me.:) happy blending .

Is there a way to define/constrain the area where dynamic paint spreads?

thanks for getting that smoke gltch straightend out. i was just starting to get use to it.did look pretty cool though,and still rendered correctly

hi, when i try to bake the smoke by pressing "Bake" in fire_pillar.blend
Blender crashes at 16 % progress. I use blender 2.64.9. rev 52764 under mac os x lion, 10.7.5

Are we allowed to use these .blend files in our own films? Are they copyrighted?

i try to make like that. but i cannot make it glow. this is my result not glowing and your result is glowing http://maherzen.files.wordpress.com/2013/01/untitled-1.png

can you tell me how to make that?

@amysidra: It's the compositing node setup. You can check my old fire tutorial for more details about it: https://www.miikahweb.com/en/articles/blenderfire#4
