Carrara Challenge #56 - "Let There Be Light."

Persona Non Grata

I'm into creating simple shapes at the moment...

 

A simple shape...

 

Decided to put it in a box and on a plinth. The interesting spot in the background has an ies added...

 

Dressed the plinth with Phong Shader and a draped cloth - courtesy of Carrara's native soft body physics engine (it's just delicious!)

 

Next, I start messing about with the composition...

 

Shaders used are my own, everything rendered using Carrara's basic photorealistic render...

Philemo - wonderful scene, gotta get me one of the cars !

Persona Non Grata aka Selina - beautiful scenes - hope you enter them !

mschack - simple but elegant !

Sorry about the typos .... ipads fault

so you posted an apology instead of editing it 

LOL

Phantom of the Basement

I am going to get one in.  G2F with Portia Hair in Flirty Nightgown.

Set, phantom, and candleholder modeled in Carrara.  Used the spline modeler for the steps and the arch hallway.

To the extent I have a tip or trick, it is remembering to use a layers list and parametric mapping to apply two different procedural shaders to the spline model that forms the upper right hallway.

Thanks Bunyip02 for your kind comments

Hi,

I woke up this morning to check the entries thread for new entries and found both my pictures were deleted. I've put them back again and this time left the thumbnail.

Has this happend to anyone before? It's my first competition, did I do something wrong? Any help greatly appreciated.

 

WendyLuvsCatz

you need to leave the thumbnail there or have it in your WIP post because the image embed links to it

you see it for a while after deleting because it is in your browser cache

Persona Non Grata

AND THERE'S MORE

..decided to give the shape some structure and created a skeleton - rather than mesh manipulation / morphs...

HOW IT WAS DONE...

• In vertex room select edge loops and faces to see where the centre of these are and make a list.
• In the model room add separate bones where these 'centre' are and orient them so that they follow the lines of the mesh
• Parent the bones into a finished skeleton
• Attach the skeleton to the mesh and create an animation group
• Check mesh deformations and tidy up (if necessary) in the vertext room

Thanks Wendy - that makes sense. I'll leave the thumbnails in for now.

@Persona Non Grata I'm liking the key light to the front left of your latest pic "..still messin'".

mschack

The final (I think)  It took a really long time to figure out how to get the light drop off in the candle playing with SSS, but it was a colour mixer with elevation blending in the glow channel that did the trick. Rendered in Cararra and all Cararra native objects except I modelled the mirror, candle and napkin (in Cararra).  Also both wood textures are from our fine friends at Textures.com.

@mschack You've captured the right balance between the light the candle is throwing off and the ambient room lighting. Looks great!

Diomede - Phantom looks great, glad the update didn't stop you !!!

Persona Non Grata - nice rigging skills !

mschack - excellent !

Sci Fi Funk

@Persona Non Grata - Two strong entries congrats. Have you thought of animating that model you rigged?

...index of refraction should influence Caustics on reflection, but I couldn't see it. But it definitely does on transparency.

These images don't have any transparency applied to the object's shader, only reflection and IOR and as you can see if intensity is set higher than the offered 1000 you can definitely see something in the caustic pass...

 

 

Caustic pass...

 

looking wonderfully organic - great idea to seperate the caustics render pass so you can see what is happening

why render caustics in a pass?  works better that way? 

Persona Non Grata

The only advantage I can see for rendering anything in a pass is for later compositing. Then you can 'colour' or blur the layers and create interesting effects. For example, the caustics layer above would look better coloured more yellow and then added to the original image...

Hope that helps, however I can't see a way to render just the caustics layer and not the whole image - if anyone knows that?

goode point but I just discovered that carrara's caustic pass is not telling the whole story - I'll post results later.

lobve your simple scene by the way - the best way to explore lighting without too many parameters

nice character :)

mschack that turned out beautifully - the whole scene has an ethereal glow

thats the  image for the cover of a novel if ever I saw one :)

finally had a chance to play with carrara ugh

 

this is a simple scene with two matching m4 figures and two spheres domes 

to get the weird tree like silhoettes I used a mandlebrot thingy in the alpha part of the shader

the main light comes from a light which just lights up the spheres only - I used caustics and reflections  to light up most of the rest of the scene  - without casutics turned on the scenes ia black

stars are in post work

 

no post work

Thanks for the comment, Headwax.  I've had so much chaos recently that I was afraid I wouldn't get any entry in.

As the theme is about light, I've decided to experiment with reflection, transparency, refraction and caustics.

I've never used caustics before so this is new to me.

Let's talk first about caustics, I'll come to the scene construction in another post.

After several tries and error, I came to the following settings:

The main parameter here is the filter size. if it's too small, you get a lumpy effect. If it's to big, the effect is so diffused you don't notice it. Also, the size of the filter is related to render time. The bigger the size, the longer it takes.

Here is the render without caustics:

The caustics pass:

The final image:

You need see the images full size to really see the effect. It's not obvious (except on the windshield), but it's definitely there.

From a physical point of view, index of refraction should influence Caustics on reflection, but I couldn't see it. But it definitely does on transparency.

custics is a neat trick.  needs idl on ?

just a bulb soft shadow & a fire in the smae spot + IDL.

the shade has add thickness & 2 shading domains:

the IN one has tile MC mixer: a color + translucency one & reflective + bump one.

the OUT has a caution for color and translucency.
