Cloud Modulation with Vue 10 xStream.

#1

Hi All,

Im currently working on a project and was experimenting with the cloud modulation capabilities with Vue 10.

Got the stuff working from this tutorial:
http://www.youtube.com/watch?v=2TGDaqs0NqM

However, i’m looking to achieve the effects of the cloud appearing only on top of the mountain and also want it to drift off as it hits one side of the mountain (like the demo they show on the front bit of the video), instead of the clouds moving closely along the face of the mountain (The end result of the tutorial).

Sadly, i have only manage to find one tutorial on this effects.
Ill very much appreciate if someone can post some links, tutorials or comment on how to achieve this two points that i am looking for.

Looking forward.

Here’s my test video:

Notice that the clouds stick with the terrain through out the whole animation.
This look like a time lapse video where the movement is shot over a long period of time, hence the cloud moves in this way.
But in real time, the fast moving cloud will hit one side of the mountain and drift off on the other side.

Hi,

If you are looking at this post and are using Vue 10 Xstream, you might have notice that your MetaNode cant connect to the Altitude Node.
That is because it has changed since the last update from Vue 9.5 Xstream.

Someone on the other forum have found a way to counter this using the texture node.
Please look at this link for more info:

(Sign up and look at the Print Screen to better understand it)

The person asking the question in that post did not push on and complete it, but it is really simple. You just need to go into EDIT and select the position and size of your terrain in the 2 different External Dependency Node.

Still looking forward to some experts advise to solve my issue with the cloud drifting and making it only appear at a higher altitude.

Cheers…

Hi

I have not really worked with the new options of Vue10, but it seems that you would need a particle system or fluid simulation to let the clouds react to the mountain in the way you described (particles colliding with the mountain geometry, getting stacked and deflected). In principle, this function would be an option in one of those 3D-applications which hosts VueXstream, and also the rendering of the clouds would have to be done with those tools of the 3D program and not Vue.

Hi Christian,

Thanks for the advise. Thats more unexplore grounds to cover.
Will look into that when theres more time.
Currently im exploring if theres anything thay can be done using just the function editor in Vue,
and see if theres any other way i can get close to the final result.

Appreciate your advise. :slight_smile:

Use two different types of cloud animations maybe? One coming at the mountain. One coming from the mountain.

Hi Shawn,

Thanks for the response. That is one way of doing it, actually i am trying to do what you have suggested now. LOL. Using metacloud to create the cloud disperse when passing by the mountains.
But it is a tedious way to try and imitate that movement.
When i was trying to animate opacity of the cloud to fade it off, i find that the material animation is kind of weird. It doesn’t create any in between frames, meaning it just ‘POPs’ and switch to my 2nd key frame.
Im not sure if its just me, or Eon materials cant be animated properly…

More obstacles ahead. Thanks for all the help and advise. :slight_smile:

There’s no tweening between keyframes? I haven’t tried animating clouds yet in Vue. But I was wondering if you tried animating cloud zones, and if zones are even keyframe-able. Then you could adjust cloud falloffs over time by changing the shape of zones.

e-on usually takes a few versions of Vue before an added feature becomes full-featured.

Oh! That might be it! I’ll try it out and see if it can work. Thanks.
