Thanks a lot for this tutorial! I've done a lot of work with Volumetrics, even started an Honors Thesis on them, and quickly concluded they weren't very suitable for efficiently getting some simple smoke. This is just what I needed! Also good job explaining getting particle size over lifetime. I hope you've posted on some of those threads, as I can confirm I spent a long time searching as well without an answer.

Great as im a plumber and have been on blender now about 100 hours , so this is good news. i modeled a xmas train wheels that revolve, emitting extruded letters modified by a hidden subdivided 'mesh deform' snug fitting soft body cubes , that holds the letters together but giving them soft body properties. i might start all over , steal your model , and in a perfect world , model it blasting through the road blocks in dover . puffing out big balloon letters spelling merry xmas to all! w black and white checkered hats blowing in the wind.

Man, the particle size change thing is awesome!

Just used this technique - very handy! One thing I did, was to edit the particle plane, copy the verts, rotate on x by 90, then do the same but rotate on y by 90, so you end up with a kind of intersecting shape where you have a plane facing in every direction. I found this helped avoid seeing planes where the plane is obviously tilted away from the camera.

@Thomason1005 8 жыл бұрын

when setting up the fade out on the smoke material you can actually divide by the particle lifetime instead of the constant number, thatll make later changes easierbut still a very great tutorial, couldnt have done it otherwise

If you have smoke texture with transparent background you can actually check use transparent in Images as planes addon to speed up a process little bit , it will setup material for you :) Just a tip, great tutorial!

I think the "proper" particle time setup would have been Age / Lifetime, Age / might screw up when you adjust the lifetime later as that could make particles disappear too early or not enough at all.

Why not add an animation of the effect at the end? It's hard to judge how it looks as a still.

Could I use this method as muzzle smoke for ( example) tank cannon?

@veggiet2009 9 жыл бұрын

with 150 transparency levels, won't that slow down the render quite a lot? I'm guess that doing volumetrics is still slower render wise, but wow that's a lot of tracing through transparency!

@3dgeneral951 9 жыл бұрын

veggiet2009 Well I agree with you but one of the purpose that wasn't mentioned is that you don't have to bake smoke (which we all know takes forever depending of your machine). This method will be VERY interresting when Blender will get volmetrics rendering on GPU because there won't be long bake times or render times ;) ! But I still think that Smoke simulator is a better option; at least for explosions and stuff like that. :) Either way thanks for the tutorial Jonathan !

@veggiet2009 9 жыл бұрын

I hadn't thought of baking. I do like this method for NPR styles though, it gives it a very painterly quality

@BIenderHD 9 жыл бұрын

veggiet2009 You could also use this with simple spheres and Freestyle rendering to give a cool toon smoke effect

@LordOdin 9 жыл бұрын

veggiet2009 transparency is horribly slow. Also light paths that go through transparent planes have more noise than they would have without... it kinda sucks because doing simple things takes forever to render. Here is a post on my blog as an example of cool things you could do if it didnt take so long lol durknfred.blogspot.com/2015/02/cycles-voxels.html

When the hell did Blender get so complicated? I remember back in 2.43 it took like 2 minutes to achieve this in blender internal with rendering and everything O.o. I remember you just slapped billboard on and changed a few settings and you were done, no messing with node editor and 40,000 other settings. I don't have the greatest computer and the fact that transparency over time for each particle in blender internal is broken makes Blender useless to me now. It's aggravating.

Good afternoon, depending on where you are, my name is Louis. I am going to be making a tutorial of my own over the next few days in regards to a hologram. It dawned on me that I used the same technique you demonstrated on blender diplom's KZfaq channel several months back to create a hologram type material using the node editor. I would like to ask your permission before starting this, as to if you are okay with me using the same node setup. Please let me know. Thanks.

@RolazoGL 9 жыл бұрын

any clue how to do this with the old Blender Internal? I got the particle size working, but that's all the control you get over particles life, the other stuf seem broken (like density).

@BIenderHD 9 жыл бұрын

RolazoGL Particle textures are definitely weird. But try mapping that textures for density to to object instead of to particle/strand, because you'd want it to effect the particle system as a whole instead of each one during its lifetime.

@RolazoGL 9 жыл бұрын

Blender HD Well, found it for density it was "generated" coordinates. But my mayor gripe is not getting the transparency over particle life to work with the old blender internal, any clue?

@BIenderHD 9 жыл бұрын

RolazoGL You can also set regular BI textures to be mapped as strand/particle. Does that help?

@RolazoGL 9 жыл бұрын

Well, sorry but not much really, they can be set but do not do much, I've been looking around and it seems that functionality is broken for the old internal renderer, thanks for answering anyways.
