I can't create different clouds on different objects because then houdini asks me for the SOP that contains the geometry to render the i3d file...
If I create different clouds inside the same OBJ and then merge them together, the i3d texture doesn't work properly.. all I get is a veeery small little cloud, instead of the majestic clouds I had created :|
I couldn't think of a way to create different textures for different clouds, unless I applied many Atmosphere objects..
Any suggestions on the most efective way to do this?...
Thanks for all the help guys
EDIT: btw, I'm creating the clouds by copying a metaball to an extruded and edited box.. this works great for just one cloud!

See attachments (H6.1nc)
It`s posible to use all this clouds within single Atmosphere object,
however standart i3dFog shader must be modified

Oops. It`s imposible without z-sorted array...but
arrays are not currently supported within VEX:(

haven't checked the attachment yet but.. how would you go about modifying such a shader? Don't try to explain the modifications, I'm just curious on how to get to the shader...
Anyway, I got it to work by using the metacloud instead of the fluffly.. but I still have to create all the "clouds" (metaballs copied to box's points..) inside one the same object and merge them together..
I had success before with duplicating the atmosphere object, but I can't find an handle to manipulate the fog object in the scene, and since you don't see the cloud unless you render, it's hard to manipulate it by changing the translation values..

Dont modify standart shaders itself!
Tools -> Operator Type Manager -> Operator Type Libraries
Find & select shader.
Right Mouse Button -> Edit Contents
Swich to VflCode tab & hit "Save as File"
Open saved text...modify...rename...install as new shader:)
Now You can tweak shader within SHOP:
Load new shader -> RMB on shader -> Type Properties -> Vex Code tab

You can create Iso Sop (3D texture mode) within Attmosphere Object

Thanks for all the help!
Gotta start playing with those shaders after I finish this project..
