At the beach a cloud has no home yes and the sun is the enemy but the natural home for a cloud is high on a mountain. Clouds love mountains or they wouldn't cling to them quite so tightly
No not with the lonely goatherds :)
Would a lost lonely cloud need guiding to a mountain perhaps to find home and family? Big brooding alpha-male :) Cumulus with the anvil and Cirrus with open arms. Misti the jealous sister
"But Misti you haven't seen the ocean how can you say that?"
Ooh the flecks of protein foam whipped up by crashing waves is called spindrift, like snow it flies before offshore breezes. A memory of being caught in spindrift on a beach at Rocky Bay near Cork when a child. Spindrift is cloudlike I mean :)
splinters sorry to be going on mate, not meaning to be hassling you at all 'WTF is he on about now?' :) I'm enjoying seeing your excellent WIP. This ^ is totally irrelevant to what you're doing right now I know but it might help your character's story-building in some way perhaps, down the line on a wet Sunday afternoon. Clouds again :)

There is a charming wistfulness about these Little Cloud images - they put me in mind of a song (by Monty Python of all things!) which has the words:
"How sweet to be an idiot
as harmless as a cloud,
too small to hide the sun
almost poking fun
at the warm but insecure untidy crowd..." |

Despite never having heard that song Wizard, you have no idea just how close that is to my original idea...:D |

Well, school's out for the Summer and, despite a heap of landscaping to do in the garden, I am dusting this one off...well maybe not dusting.:D
Anyway, my attempts at a bubble material in Vray are not working well...looks like he is managing to blow a goldfish bowl with his 'catapult come bubble blower'.
Any suggestions appreciated, the last material suggested did not work so well...:o |

well.. it was only a sugestion.... Start there - remove a bit of the refraction and that should help. I also think that mine looked better because it was actually a sphere with a sphere cut out. it was only about .005 thick. ;) |

I seem to be a little stuck on the bubble but moving on to a different problem. I don't have the documentation at hand but does Vray support texture maps?
Reason I ask; this image has the raindrops mapped as a transparency but I cannot get the raindrop texture to show. Only an experiment for now but I really want to use Vray for this project. Can this be done? |

Whoops, my mistake...I had a glass shader on the plane....:o
Seem to be answering my own questions a lot today...:rolleyes:
As for the bubble texture Kena, I really appreciate the help, even if it did not sound like it. Really trying to get that oily look with the rainbow colours though... |

Nice work Splinter...
Can i comment something??
The drops looks flated, i recomend use less drops textures on the plane but add more planes into diferents Z values to fake like the drops are more volumetrics..
Good work! |

Very nice Splinter!
Good picture for my kid's room.
One small comment from my experience then I worked for meteorological office:D . Flip the drops horisontally. Now wind direction is from right to left and cloud should be at the left side from the boy. |

Very nice splinters
As a metior meatier weather-watcher can I mention that raindrops become perfectly round after a short time falling? Drops of water seek their most compact form (mathematicians call it the beachball) under gravity and quickly form perfectly round drops - in the same way that soft metal (lead) is worked into round pellets by dropping the liquid form from height into water
It's an added-value hook "Why is that?" into physics for the smaller citizen :)
Speaking of rainbows it's because raindrops/cloud particles/floating water drops are perfectly round that we see the prismatic effect. If raindrops were not perfectly round there would be no rainbows...
Artistic license beats all that dry science mind. Wet :)

Looking good Paul, but to my eyes you've got a few too many droplets. Its looks a bit crowded. Nice mood to the whole scene though.

Cheers Steve, made some changes but I am not too happy with the rain yet.
Anyway, I roughed out a story and this is how I mess with pages to get an idea of layout. Text might be cropped if this was a double page image but it is just a visual 'doodle'. |

This is a nice image Splinters.
I'm thinking you're right about the rain still being a tadd off though. I think I'd try a reflective semi-transparent metal shader for the drops myself as opposed to using a glass shader, but that's just me probably, I have better luck with those.
I made a quick sketch suggesting a sweeping rain path that might work for this image given that the cloud is "thinking" about being elsewhere than where he now is, what do you think?

Here ya go Paul...
This took a while to make...;)
It's a brand new Vray Bubble Material... it will probably need tweaking to get it just right in the existing lighting environment you are already using for your scene, but it does have nice potential for your specific needs here I think.:)
I put the material on a sphere in Workspace side and saved it via Truespace7.51 as an Rsscn file in my library stack. Then I renamed it, and reloaded it into Workspace and changed to Modelside which allowed me to save it as an "Archive." This way all the textures used for Vray in the material itself and the GI are all saved together into that same folder.
Then I zipped all the files in that folder and also added the jpeg file (used in this post) to the zip as well.
Hopefully it will work out for your needs.
Cheers,

Brilliant, I will try it when I get on my work PC.
Hopefully you were already doing this and didn't do it just for me...:rolleyes:
Much appreciated either way...:D :D |

I had trouble with the material; it was just black when I loaded it but I tweaked a bit and I am much happier with this...although I need to tweak a bit more.

Hmmm... I wonder why it's so light on my machine and so dark on yours, makes me think I could have bad gamma on this end. On the other hand, I see that your scene's overhead sky is much darker than the one I used in GI for the bubble material creation test renders, and that could have a lot to do with it, as could the Index of Refraction or the fact that I didn't use caustics.
What strikes me as strange though is when you say it was black when you loaded it, since it was extremely light in shade on this end.
In any case, feel free to alter the input images or replace them of course, it appears you have it looking "filmy" like it should at least, just the darkness left to tackle and you should have it down fine!
As for all the work that went into it, I got several additional (non-bubble) materials out of the effort as I worked on that one so we both benefitted from the effort for sure. I usually save decent versions of stuff in the process of arriving at intended versions, it's becoming a good habit I think.
Well, I am happy at least with the filmy irridescence of that material, at least that part was spot on, hopefully a few adjustments to the various transparency settings will be all you need to perfect it for that scene.
If I stumble across a more promising alternative material I'll let you know, but the differences between our two systems may come into play again with that.
Since everybody else here can also download that new bubble material now maybe someone with better system specs than me can help with that too.

looks awesome, but im not sure about the bubbles, they look pretty solid to me. They are much more see through than you might think:

Have you tried Tom Grimes' Shaderlab2 'iridescense' or 'iridescence2' shaders yet?
Filmy little rainbows...mmmm
----------------------------------------------------------------------------------------
This is a Vray rendering so I don't believe they can be used for this.

OK Paul, I may have the solution here after all.
The more I study this it appears to me that there are four distinctly different reasons why the material I made for you isn't working in your scene. I've already solved 2 of these issues but the remaining 2 require your assistance.
I'm attaching a Zipped COB model to this reply which you will need to load and add to your objects library.
A) Load the object and save it to your objects library.
B) Make a copy of the scene you are using here (without this new object) and be sure to name it differently than your existing scene.
C) Create a new blank scene context.
D) Load the copied scene with the new name.
E) Delete every object in that scene apart from the environment itself, so keep the ground and water and background plane / dome, but remove the boy and all objects associated with him.
F) Load the COB model I'm providing here into that new scene.
G) Switch to Modelside, and save the scene as an "Archive."
H) Close trueSpace and create a Zip File of the contents of that folder, ie" Drive:/trueSpace7.5/ts/Archive/name_of_new_scenefile/*.*
I) Post that zip here and I'm pretty sure I'll be able to make this all work.
Problem #1 was using the wrong transparency method in Vray.
SOLVED
Problem #2 was using the wrong reflectancy method in Vray.
SOLVED
Problem #3 was using the wrong GI settings, which requires you provide the Zipped scene Archive so I will have the right existing ones to work from.
Problem #4 was using the wrong material settings, which again, requires you provide the Zipped scene Archive so I will have the correct environment in which to determine all appropriate material settings for that particular GI scene.
Here's the Cobfile Zip. Once you save the new scene as an Archive through Modelside all the Vray settings you are using in that scene are saved along with it and I'll be able to make this work for you.

Dude I'm working on glass and I saw the something-alpha property tucked away in one of the panels, a-alpha or somesuch. I tweaked that and the greyness was adjustable via that parameter, before that the glass had that dark-grey tint to it that you're looking to fix (or have solved already perhaps). In the Material Editor sample it looked stubbornly dark-but-transparent before tweaking that. This would have been from DX9 materials probably

For the way the scene is lit, at the moment the best results are using 3DVD's oily texture on a mirror reflectance with half transparency then enabling HDRI but that is causing a massive hit on render times along with the GI that is already there but at least I have new hope now...:D |

Well the good news is...I found a shader that works just fine...
Bad news; it's a simbiont and does not translate well to Vray.....:( |
