Dirty and cheap way would be using particles (and converting them to mesh as Corona doesn't support them yet).

I must leave it like this.
Actually i came up with a crafty way of doing the waterfall and came up veeeery cheap to render, and looks acceptable for my needs. And at a 1 min per frame  1280x720 is quite remarcable.
I must say corona still amazes me.

Just grab some random waterfall video from vimeo, cropped in after effects. Then extract the white color leaving just the waterfall.
Exported as png secuence with alpha channel.
In a plane sligthly modified to the shape of the waterfall mapped the png secuence in a corona ligth material with opacity. WORKS LIKE A CHARM!!!!.

Check this preview:

*UPDATED*

DISCLAIMER: ABSOLUTELY  no post pro where harm doing this preview... just Corona raw crude awesomeness.

Is just i tried the realflow approach but that is quite expensive. And the meshing are not satisfactory at all. Aside the foam and bubbles /splashes needed for realism could'nt  find a way of rendering. It seems that Krakatoa does that... but... loooong shot for something that simple... so i fake the shit out of it.

Cool model for testing but I think you waster its potential. The feathers could produce some really interesting results, how about adding translucency to them? The rendering seems overexposed, burned, but there are no visible shadows, no background, just the model floating in space.

Well... after tons of trial and error finally i got one that makes me proud enough.
I have been working in this for several days by now, and i think i nailed one kind of feathers.

Thanks maru for the feedback i think i could not have done this without your advice.

I let the scene here... someone maybe has the time to better improve this. Or at least make a pillow figth XD.

Another a little more complicated feather stuff.
It's kinda tricky to make good looking feathers.
It looks good from close range or far range but i could not achieve both.
Must keep testing.

Corona is fun to work with!

I decided to put feathers test aside until i found or came up with a better way of locating feathers over a surface than forest pack.
Today is time for a little fun.
This time working on a common Chilean beverage called "mote con huesillos", we drink that a lot on summertime.

Corona is awesome.
As usual... and as exercise, no more than 10 minutes of rendering time.

borisquezadaa, about positioning feathers,  have you tried standard hair&fur?

It works pretty well IMO.
I have a tutorial about exactly this if you want it I'll post the link here.

Hi juang3d... post the tutorial link so i'll have a look!.
Its possible to affect scale as well as orientation with hair and fur?. If so, maybe i can use it cause rigth now i'm a little stuck.

Hi. Very nice renders. I think the camera angle from the first one is better, as well the spoon. But very nice droplets on the second pic.

Time for some really sexy caustics.
+1 for a way to isolate just those to compose later!!!...
I compared them with the real glass and as usual, corona kicks all kind of asses. (minor firefly cleaning required).

And i came up with a workflow to produce this in a comfortable way.

Yep, what's that ? I suck at caustics and can never get them to look good in pool.

I think Corona is great for a product shot so why not try?...

I call this masterpiece "Biped party hard". XD.

As always is ridiculously easy to get this quality in no time. (As always never more than 10 minutes per render, cause hey!... life is short!).

Blood test using sss from daily builds. First time user.


Some post to add motion blur, just to find out that Corona can do motionblur from mesh secuences in a way (related to the Shutter speed). Duh!.

Attached are the settings used for blood in Realflow (you can always play and improve).
And off course the material used for blood in a .mat file 3ds Max 2014. (It work with daylies i'm afraid cause use some sss magic).
YOURS TO PLAY AND IMPROVE

Later i'm gonna find how to upload to Corona material library.

I dont do hyper high resolution of my random stuff sorry. They are just tests.

Today an idea to generate heat haze from arbitrary sources that came up after looking some post pro made at Jeff Patton renders made by others.
Looks promising, attached a small animation of the effect. Needs a specific setting in material and geometry.



Wish there is a way to enter a value like 0,999999999 in the glossines slot. XD.

Hi Boris,

I'm not sure but I seen somewhere an After Effects plugin for make that "heat haze" effect. And I think to simulating in PS it's not a big deal, but I'd never tried... :)
Holy Corona : the materials is the clue.

Yes i did a simulation.
But the trick was in the mesh. Is necesary to untick "visible to reflections/refraction" in properties or you will en with some nasty dark edges.
Also the material... it would be nice to put IORs of 1,0001 like reality or glossiness of 0,99999 but we get only 3 decimals. XD.

Atached scene with setup and one frame meshed. (The mesh sequence is way to big to put it here).

Also the material... it would be nice to put IORs of 1,0001 like reality or glossiness of 0,99999 but we get only 3 decimals. XD.

You can set the spinner precision up to 10 decimals in the max preferences ;)
Any sufficiently advanced bug is indistinguishable from a feature.

Cool. As it happened, i'm listening Andy Weir's "The Martian" audiobook at the moment, so it's nice to see rather familiar landscape :]
