As long as I'm posting tonight, thought I'd let you know that the heavy node builds that our only come out at night friend ogre con-cocks not to mention Mr. Lamposts builds, are much more friendly with the latest build!!
I could barely get this out at 640X before!


The contrails look really good but I am having a very difficult time believing this was all rendered in TG.  Painted in Photoshop maybe?

No, the only thing I did in PS was convert it from an exr.

Dusty trail

Oh, I wonder if this could be used for a dust storm?
So this is Disney World.  Can we live here?

Thought Ogre would be by but I don't see why not, I'm not much with these big nodes but play with the settings.

Ogre

Sorry, long weekend.  A dust storm would occur over a large area so it would depend on what you needed.  This particular mask may not be good for that but a modified one might.  This mask would probably be good for snow blowing off a mountain or the like, a smaller local effect.

Here is a quick WIP of snow blowing off a mtn top with the input parameters.

Now, that's really cool. Those same settings look like they would be good for a steam train chuffing by too.

Wow, nice adaptation there, Ogre.

Thanks,  I am doing a "final" modification on the functions and will release a V2. The inputs will include;
Initial X
Initial Y
Initial Z
Final X
Final Y
Final Z
Initial Radius X
Initial Radius Y
Final Radius X
Final Radius Y

The change between initial and Final positions will be done linearly. I will also make a version so it is planar in XY, XZ and YZ so Mandrake doesn't get confused. ;)

wow nice pic ogre, and that would make an awesome steam train engine trail.

Just uploaded the current version to the Ashundar DL section. I included a few brief explanations of the functions used.

So, If I used 3 of these node systems, one for each of the Thunderbird 3, engines, would I use 2 merge shaders or plug them all into the density shader?
Did this all over lunch? hehe

Lunch - About the only time I have now days to play!

To generate multiple trails - Yes plug into a merge shader like in the original flash rocket contrail clip.  I'll look into simpler ways to make multiple trails but for now that is the answer.

I attached the base clip file here. Use that until the file zip is uploaded at ashundar.
