Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

HELP: Looking for photorealistic thruster tutorial! Any suggestions?
I have been looking through all the material here but haven't been able to find anything on what I am after. I am chasing tutorials on creating photorealistic missle thruster effects.
Can anyone point me toward a tutorial that is or touches on the subject? It is easy to say just use particle or just use voxels but I am actually looking for something that will help me with the realism so any suggestions would be great.
Preferrably for Maya!
Thanks much appreciated,
Nick.

Other than the "Exploding Mig" video here at SM that I did a LOOONG time ago, we have no tutorials specific to what you are looking for.
Having said that, look at the image below.
This I did in Maya with a simple shader setup on SWclouds rendered out with Mental Ray.
If you would like I can slap together a small step-by-step in the next few days on how I did that.

one uses the RGB values of an image to push the pixels of another image
in after effects go to effect/displacement
in the effects panel go to/ displacement map layer
choose your displacement layer (the one you have already made using grey scale values, in your case i imagine it to be 'wave like'??)
horizontal and vertical displacement (you will see the in the effects panel of your displacement effect) will work with colours (when you look at it yu will know what i mean) but with a grey scale it makes no difference.
its simple, just play with that for a while
best i can do.., got to go!!
opps, i ve been shaped so i didnt see you are using fusion.., anyway.., its the same thing. there must be a displacement node in Fusion.., not sure whats it is called.., ill look
dum de dum
yep, there it is.., warp/displace
mess with that..,
take it easy and life will be easy

rageMETEOR_DEMO scene file
Feel free to use/edit it to learn from.
The shot was portaying 2 meteors falling from the sky in front of a moving camera and smashing into a few buildings.
I basicly started off with 2 simple omni emitters parented to animated spheres.
I adjusted the emitters to only emit software cloud particles for about 3 seconds of life with a bit of variation.
The spheres had their Primary visibility off, as they were just used to animate the emitters.
I added one or two expressions on the particle shape to give some scale over time, and some death randomness.
(its been a while, so just check out the particle shape to see what I did
)The shader was based on a lava shader that I made that contains a 3d fractal and a Stucco node.
The For this scene I animated the X-translation of the 2 3dtexture placement nodes to give it some "seethe" or "convolve" to make it look like the fire-cloud was rolling and had a sense of thickness or volume.
Then quite simply, I rendered the trails in Mental Ray as separate passes, and in my compositor I adjusted the color a bit more and added a subtle animated VERY low noise displacement to the plates to give a little more sense of roll or convolve.
The color adjustments I made were pretty simple.
I adjusted the levels a bit to bring out the black/darker color.
I also sampled the red and oranges to overlay back on top of themselves to over-accent the dark colors giving more thickness to the trails themselves, and that also gave me more control over the bright red/orange gain so they wouldn't blow-out and seem too bright and "glowy".
Then I comped that all together overtop of the other plates and the natural life transparency Vramp in the shader allowed for a good blend with the shot.
Here is the scene file.
Feel free to ask any questions, but remember, your shots WILL be different, so you MUST remember that particles and dynamic simulations are usualy trial and error, so SAVE OFTEN and save MANY variations so you can go back to the beginning if need be
Good luck!
