ParticlClouds Package v2 (Volumetric Clouds!!)

This is version 2 of my cloud package:
The Main new feature is a fancy real Volumetric Effect.
You can control the color of the cloud and the highlight!

Demo1
Demo2


This package is a bit heavier on your system then v1, if you need thousands of clouds then I suggest you try out v1.
If you want more accurate looking clouds, v2 is for you. :wink:

now go download this package!!

 

this is nice One question tho... Can I use it for my game?

 

yes 8)

 

These are awesome. You do fantastic work on these.

I'll bet you could do some fantastic fog as I love your work on these clouds.

Do you have a PayPal account so I can pay you to do some fog for me?

 

These are fantastic.

One question: Do they cast shadows?

 

I like them a lot, but wish you wouldn't use Simulate In World Space on the particle emitter. When set that to false, you can parent them to something else and give a nice wind effect. It's time for lunch, but if anybody can't figure out what I mean, I will explain it later. Oh, and these make for some nice swampy fog.

 

These look fantastic!.

I would suggest to put some "parts of clouds" over each other because they look a bit "planar", like a thick planar area.

I dont have in my project a real need for volumetric clouds, but yes could be a hot feature if these could be emited as dust or smoke trails to use as dust that comes from cars when driving in a dirty road or when braking hard or burning tires.

Excellent work anyway and thanks for sharing!!!

 

Hey,
they look really really nice! But theres a problem if the camera goes too far away from the clouds. After a certain distance the get darker and darker until they get black. What can i do to prevent them doing this?

 

Hmm does this only happen when Fog is on?
I just noticed the shader has a set fog color

Use this shader:

Code (csharp):

1. Shader "Particles/Alpha Blended" {
2. Properties {
3.     _TintColor ("Tint Color", Color) = (0.5,0.5,0.5,0.5)
4.     _MainTex ("Particle Texture", 2D) = "white" {}
5. }
6.  
7. Category {
8.     Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
9.     Blend SrcAlpha OneMinusSrcAlpha
10.     AlphaTest Greater .01
11.     ColorMask RGB
12.     Cull Off Lighting Off ZWrite Off
13.     BindChannels {
14.         Bind "Color", color
15.         Bind "Vertex", vertex
16.         Bind "TexCoord", texcoord
17.     }
18.    
19.     // ---- Dual texture cards
20.     SubShader {
21.         Pass {
22.             SetTexture [_MainTex] {
23.                 constantColor [_TintColor]
24.                 combine constant * primary
25.             }
26.             SetTexture [_MainTex] {
27.                 combine texture * previous DOUBLE
28.             }
29.         }
30.     }
31.    
32.     // ---- Single texture cards (does not do color tint)
33.     SubShader {
34.         Pass {
35.             SetTexture [_MainTex] {
36.                 combine texture * primary
37.             }
38.         }
39.     }
40. }
41. }
42.  

This shader ignores the Fog:

Code (csharp):

1. Shader "Particles/Alpha Blended" {
2. Properties {
3.     _TintColor ("Tint Color", Color) = (0.5,0.5,0.5,0.5)
4.     _MainTex ("Particle Texture", 2D) = "white" {}
5. }
6.  
7. Category {
8.     Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
9.     Blend SrcAlpha OneMinusSrcAlpha
10.     AlphaTest Greater .01
11.     ColorMask RGB
12.     Cull Off Lighting Off ZWrite Off Fog { Mode Off}
13.     BindChannels {
14.         Bind "Color", color
15.         Bind "Vertex", vertex
16.         Bind "TexCoord", texcoord
17.     }
18.    
19.     // ---- Dual texture cards
20.     SubShader {
21.         Pass {
22.             SetTexture [_MainTex] {
23.                 constantColor [_TintColor]
24.                 combine constant * primary
25.             }
26.             SetTexture [_MainTex] {
27.                 combine texture * previous DOUBLE
28.             }
29.         }
30.     }
31.    
32.     // ---- Single texture cards (does not do color tint)
33.     SubShader {
34.         Pass {
35.             SetTexture [_MainTex] {
36.                 combine texture * primary
37.             }
38.         }
39.     }
40. }
41. }
42.  

I have reuploaded the package with the correct shader!

 

Thank you, that was it-

 

these clouds are awesome. thank you.


On a kind of similar note, would it be possible to write a script that actually makes the particle color based off the vertex color of a mesh particle emitter? I'm thinking of kind of like a 'baked cloud shadow'.

 

You're a hero!

 

Epic!

 

Wow!!Very cool.Thanks for share.

 

This is really beautiful! I'll try it later.
Thank you for sharing this.

 

Beauty,,, thanks for sharing !!

 

holy!

 

Another epic win for the freeware world. Be sure to check you name under Heaven or Hell Credits friend! (as soon as it have one :> )


PS: How can i change the clouds position? they seems static in my project. =(

 

Look really good!

 

Help me Ikke i really want you to be on my project´s credits!

My freeware friend!

=)

 

Hi Ikke,

These clouds are great!! Thanx for sharing!

I wanted to change the lighting of the clouds according to the position of the lightsource for my project.

So I've made some adjustments to your script, maybe you or someone would find it useful so I thought it'd be good to share it.
My experience as a javascripter is about 25 days so forgive me if there are some mistakes. Also, I'm still working on it and will post the final script with the screenshot of the results.

Here's the code:

 

ok I know how to fix this but I can't find the download link... Could you post the volumetric cloud script up here please? Then I will make the changes...

 

There's a unity package file attached in ikke's first post.

 

Awwwww man.... I feel stupid now

Anyway... Here is the simple version... I found there was a lot of stuff in the code that was not necessary.

Code (csharp):

1. var CloudColor : Color;
2. var CloudHighlight : Color;
3. var offset = 0;
4. function LateUpdate () {
5.     var particles = particleEmitter.particles;
6.     for (var i=0; i<particles.Length; i++) {
7.         particles[i].color = Color.Lerp (CloudColor,CloudHighlight,particles[i].position.y+offset);
8.     }
9.     particleEmitter.particles = particles;
10. }

Just paste this code over the old code... Then in the cloud prefab make sure simulate in world space is set to false...

Should work and hope this helps!

 

how can I make them move like in the demo?

 

Beauty,,, thanks for sharing !!

 

OMG dude this is pretty cool, I love the work you did here. I'm gonna refer you!

the demos were great, but i was wondering how you got the fly script that moves with the mouse.
I have been looking for a script like that for a while, could you possible give it to me at gunujha1(at)gmail.com?
Thanks!
and great work man
