I plan to make a dune, light wind flow away.

than some turbulence, more and more strong, finally sands swirl to a sand storm.

But at first, i really dont know how to make a good sand flow effect, it's easy for maya, but hard for houdini for me. somebody could tell me some tips or give me some advices?

I made a hip file but how should i do can make it better?

I try to render it ,but I rendered suck…

Have it any tip to render it better? sprite or just use particle?

I would say you should look at the FX Tools shelf and check out the Heavy Smoke setup. This might be a good way to render it.

Cheers,
Jason

PS. You must download this Shelf yourself - do you know where to find it?

no , I dont .

Can you tell me?

in the very top right corner of the shelf there is a “+”
click it
under New Shelf it says “Download Shelf”
click that
a new window will open
select FX Tools
select Download at the bottom (leave the default destination)

This is my target effect's movies,

this was made by maya, I think Houdini will make it better.

What should I add in this scene will be better?

I have download FX TOOL, but I really dont know hot to use it.

I select my particle and press enter, nothing happen.

Where I done wrong?

I made a new one…but this hip file havent clear up, forgive me about this.

by the way , I still cannot use FX TOOL, who could show me step by step? plz!

I have had particle dynamic, but I need more detail like my first reference picture.

Thank you all, I love you guys.

Just one more render trick and tip!

I try to make fluid fast , but I notice that are hard to keep its shape.

I want them move fast and still keeping their shape.

What attr should I set?

no one could explain it?

I would add a copy node and copy metaballs to the particles. after that I would add an Isooffset node and change the output Type to fog Volume, and the Mode to Metaballs. After that I would raise the uniform sampling up to around 60.

Hope I could help you.

Sorry for my bad English.

another problem here,

metaball with volume fog was renderedd like a black box….

btw,

my volume meterial all cannot work by mantra.

where is the problem?

my OS is win xp 64 bit.

How do you apply the Material?

I would apply the Matteriel by sliding it over the fluid box of the Volume! Or apply it manually in OBJ level, by going to the Material Tab.

You can't apply an Material by just sliding it over the Volume..!

this topic have a good idea I wanna add.

but I am not sure how to make particles collision self? or they were replaced by some small objects?

Are these two different way all could make it happen?

I tried to make something like it in my project, but I can not make them be influenced by forces, such as wind.

If I use particle and replaced by an object, then I notice their edges never collision each other.

If I use DOPs and make an object creates objects by expression in “creation frame”, such as “ if($FF%10==0,$FF,0) ”. They just have a great collision but no force can influence themselves. They run like a robot.

How come ? and what should I do?

someone can answer me, please?
