Some Help with the Destruction of the World

[darthvader]

So the problem is that when the contrail enters the atmosphere it puffs out and gets distorted from the contrail mask. I've tried changing the density, cloud fractal and coverage adjust settings but nothing works. Is there any way to get rid of this?

Very nice work so far - it looks like you're doing something similar to what I was working on. However, this bulging is quite bizarre. Have you checked to make sure that you have base wispiness/softness set to zero? Are there any other density fractals acting here? A shot of your node setup and/or a clip file might help clear things up.

Looks great to me and at first I was wondering "How did he get it to blur just at the right place?" Render it BIGGER err please

<edit> looking at it again I'd like to see some sort if sonic boom shock wave as it enters the atmosphere, maybe a couple of rings emanating from the point of atmospheric entry. </edit>

I like the atmo-distorted effect of the contrail here, it looks like it should do that when coming into the atmosphere.

I posted that question over at Ashundar awhile back. The TG team scratched their heads and we agreed to call it a feature :-)

I found that really extending the cloud layer and only working in a small part of it the feature dissappears.  (i.e. If I want to work within 0M to 1000M I set my cloud layer so it runs from -1000M to 2000M or something like that.

Is this supposed to be a Meteor or a Comet? A meteor wouldn't have a contrail until it entered the atmosphere, a comet on the other-hand would. Great image by the way.

Here is the node screenshot. The clipfile is just the standard contrail version 3 by Ogre (thank you very much for making it ) available over at ashundar. While there are other density fractals in the image none of them are modifying the contrail...I may just have to make the cloud layer even taller than it's currently huge 200,000 meters.

If course I will render this bigger but you'll have to give me a little time, I'm not nvseal si I can't whip out amazing planets like it's nothing

Oh and I guess it could be a comet it doesn't really matter, we just want some destruction!!!

Just outa curiosity have you tried a render with "Enable ray traced shadows" OFF ? Prob nothing but it only takes 10min to find out.

ray-traced shadows were off in that render...I don't know why I have the shadow, but Ogre's suggestion of increasing the depth of the cloud seems to have worked

[moodflow]

I agree with what the others said.  Great image and I think that bow-out adds a needed touch!  Its like some type of shock explosion point which would likely happen.  Though I know its not fully under control, I feel you should keep it in the image.

The shadow is from the cloud, not the actual atmosphere, although, it shows in the atmo' because sunlight being occluded by clouds casts shadows across it. Ray-traced atmosphere shadows are easily faked(not in all circumstances, obviously) with some well placed invisible clouds... Like my wee meta-cloud objects, for instance.

I don't know if your system can handle it but you could always start two more contrails from the blur down to indicate a split up with two smaller impacts.

[darthvader]

I have some good news and bad news, the good news is that I started to like the puffy-ness where it hit the atmosphere, the bad news is that once I got rid of it I can't get it back, so I've compromised and made a puffier contrail. As for Mandrake's idea of multiple impactes...I really like it, and I'll see what I can cook up.
