Blender 2.5 Volumetric Clouds Test (WIP) HELP!

Quick render demonstrating a problem with Blender 2.5 Alpha 1 volume material. The scene is lit by one sun lamp and one hemi lamp. For some reason I can't get rid of the flicker. If anyone else has played with volumetrics and can help, please let me know. I've tried everything I know... :(

Addendum: I just discovered pasteall.org!

The .blend file for this is now uploaded there at:
http://www.pasteall.org/blend/2464
and should stay there for about 5 weeks, I'm led to believe.

Feel free to grab it and play with it. (those now laughing should be thoroughly ashamed of themselves!)

Please tell me how to do clouds this. I am specifically trying to make clouds for a planet (im doing texture upgrades for darkspace)

@Uhmari Add cube sized dimensions you need. Add a volume material to it with density 0, scattering 4, reflection 2 and step size 0.05. In node editor, click textures button, add a cloud texture node, select "hard" and set depth to 6, colour 1 black colour 2 white size 1.1. Connect to convertor math node "greater than" connect to an output node then adjust math node value to how you want clouds to look. In material textures select your node output, map to generated co-ords and check influence

@Uhmari If that makes no sense, a link to the .blend file is in the video description. Have fun dude! :)

It could also be that you have two particle systems at the same place and that's like double vertex.

@TheRobbi5 Hello mate, nice to hear from you again. :) No, it's not a duplicated verts issue (and I'm not using particles). There's only one object which is a big, flat cube using textures to modifiy a volume material. I think I found out what happened though. There's an option under volume material called "light cache" which speeds rendering up but loses accuracy and that seems to be causing the flicker...

[TheRobbi5]

It seemed to me like a lighting problem. I liked the modelling though

[alanpgoodwin]

@TheRobbi5 Thank you bud! I tried all sorts of stuff with the lighting. I think that there may be an issue with environment lighting settings and volume materials. I'll keep coming back to it, 'cause it could look so cool if I get it right.

@Uhmari there is a better way to make clouds than what that guy told you you can go to user preferrenses under object add on settings and just enable cloud generator.

This is beautiful - not only do I love the clouds and shadows, but the golden hills. Reminds me of fields in the fall. Really sweet Alan!

looks like it is underwater...

@darkcg79 "Alpha quality is only for testers", where is that statement?
