Cool Goldenfrog! How did you do that? Id love to know XD. Oh, and Tom, thanks for the link, i will definitely check it out!

Thanks Nola, I'll write up a text doc in a minute.

I'll assume you know how to do smoke in Blender. If not, I can tell you. Anyway, I assume you know that you need a domain and a flow object. Set the domain resolution to 80, and if you want, check "Dissolve" and change the time. (The time is measured in frames). Then, go to Smoke High Resolution and change that res setting to 2. Change noise to FFT. Then go on over to Smoke Cache, and hit "Bake All Dynamics". This will take a while.
After that, save your model. Now you can hit ALT+A, and watch the animation. Esc. stops the anim. Now, your smoke won't show up in the render. So you need to add some material settings. Add a new material (Not texture yet) and set the type to Volume. It's above the preview of the material. Turn the density to 0. Under Shading, turn Scattering to 6, and Density scale to 6 as well. Also turn the step size (It's the last thing on the page) to .01.
Then add a new texture. Change the type to Voxel Data. Under Influence, check Density. Under the Domain Object, select your domain. Then, add a new texture. Do this by by hitting the checkerboard below your current texture. (The topmost window on this page.) Call it Fire to avoid confusion. Also set this to Voxel Data. Go to Colors, and check Ramp. Make a white core, remembering that the right part of the color band represents the bottom of your fire. Then, make a color band, that ends in an alpha value of zero. Again, set the domain object to your domain. Under Influence, check Emission, and set it to 5. (Youll need to type that in; the slider won't let you go past 1.) Do not confuse Emission with Emission Color.
Now onto the compositing. Go over to the Node Editor (Found on the bottomm toolbar where a picture of a white cube is. Click on that white cube and you'll find an option called Node Editor. Select that. So now you are in the compositor. You'll see three small buttons at the bottom of the screen. Select the one with a pic of a cylinder and a sphere. Then hit "use Nodes". Now, let's get one thing straight. The output of a node is on it's right side, and it's input is on it's left. Now. You'll see a node called "Render Layer". It's name is pretty self-explanatory. Hit Shift+A. Add a RGB curve. Then, and a glare node. Connect the glare's input to the output of the RGB node. Oh! Also, make a steep S bend on your RGB curve. Use CTRL+Clicking, to add some...I guess we'll call 'em "bend points". Move these around till you get an S shape.
Ok. So where were we? Ah, yes we were connectng the glare's input to the RGB's output. Also add a blur node. Change the type to Fast Gaussian, and change the X and Y values to 10. This makes a blur 10 pixels wide.
Cnnect the blur's output to yet another glare node. Make the type of this glare a Fog Glow. Change the size to 9, and threshold to 0. Now. Lets go back to our RGB's output. This already has your blurs input connected to it. Now, make a forked connection, and connect this to your OTHER glare node. Make this type be streaks. Keep all the settings, except for the threshold. Change to 0. Ok. Now add a mix node. Connect the output of both your glare nodes to it's input. Then hook up a composition node and fork your connection and add a view node. Hook that up to your mix's output. Ok.
If I've lost you anywhere, feel free to ask me, or ask me to upload the .blend and you can rip it apart and see how it works.
Wow. I've typed alot. This is amazing. Made even more amazing considering that I have a cold at the moment. Whoa. Ok! Talk to you soon.
-
Well thanks! Ill try that when i get a sec
I assume you mean 3D smoke? Because i watched a tutorial on that. But anyway, thanks! Ill tell you if i need any more help 
Oh and i will upload my result later XD -
Yep, it's 3d. Cant wait to see what you do! Oh, and remember the concept of initial velocity. If you create a particle system, you can make the smoke particles inherit the particles velocity.
-
Thanks, maybe you should post the file here in advance that way if i (or anyone for that matter) needs it, it will be there. I say that because i see confusion emerging in the future
-
Errrr...Actually I cant attach a .blend. Sorry.
-
XD Np! If you want, you can upload to rapidshare or mediashare and just insert the download link in a SCF post! But anyway, what i was going to say was I m currently working on a neat animation which is supposed to look like a star emitting some sort of radiation (maybe because of the thing i am about to mention) and that radiation going into a quasar-like object! Neat-o XD Ill let you know when i finish, i think i got a good thing going here XD Now waiting for that render to finish xD
-
All righty then! yOU USING SMOKE PARTICLES? Aww...Caps lock strikes again. BTW, what are your comp specs?
-
I have horrible Graphics specs XD Well, its meant for 2d xP. I am having trouble with texturing and stuff, maybe i could get some help from you xP I need to show you the vid. I cant get the particles to look like particles xD it looks like a smoke cloud. xP Help! XD
-
Um,, can you give me a screenshot? I don't quite know what you meant.

Hi guys,
Being in the holiday spirit, I decided to do a little Christmas lights, and ornaments for a CG Christmas card. Once it's done, I'll show it to you!
-
Well, Ill show it to you closer to Christmas. For now, here's a ship I made in Blender. It's a lot of fun, and the compositing really adds to it.
-
Looks comfy cozy....? xD Nice ship! Looks like it is made out of leather or something though TBH. =|
-
Yeah. you talking about the irridescence?
-
Uh, yeah, so here's a thing I made. It's a space ship's interior. It took about 4 hrs in total, and is the most successful blender work I've ever done.
![Yep. It has a "cozy" feel to it XD](/uploads/imported_attachments/NwEM_0050.jpg "Yep. It has a "cozy" feel to it XD")
-
Oh, yeah, and btw, any questions? Comments? Want to show off your work? Please post it here!
This post is withering and dieing as we speak. -
Guys?

I had a question that I'm hoping someone can answer. I've been starting to use the arbaro tree generator and am pretty happy with it, but when I bring it in to blender (.obj) I can't figure out how to texture the leaves. I was hoping they would be instanced (however blender would handle/call that) so that I could map 1 leaf and have the rest follow suit but either its not working or I'm doing it wrong. Then I thought I might be able to stack all the similar (exact same) leaf meshes in the uv editor and apply an image to the lot of them, but that doesn't seem to be working either.
Any ideas as to how to do this or is there a better way to texture a tree?
I've watched this tutorial on making trees -- and it seems like a decent alternative, although I'd still prefer to use arbaro -- but it doesn't address my initial question. -

Some of my recent work done with Blender and rendered with yafaray
