Lighting Challenge #1: Fruit Bowl

#181

I agree–excellent! My only crits are that the specs/reflecs on the orange look a little tight, and the arrangement of the grape in front of the pear looks a bit odd.

#182

Really nice work on the materials, Holle! The lighting is good, but not very dramatic?

#183

I think maybe some are intimidated to critique with you in da house, Jeremy but I’m not shy.

Master Zap: Ya got mood. No question. I agree with dbates about the apple leaf. It’s an unfortunate camera angle that lines them up and the similarity in colors makes them blend into one object. Personally, I have trouble understanding the rays behind the cloth. What’s going on there? The way they fall on the cloth and the objects is certainly believable, though.

General question: How are you guys texturing the cloth? I didn’t see a UV map.

3Dworks: Is that a basketball dimple bump applied on top of the orange? An hour to render on a Quad? With EI?

holle: I love your render. The only thing that detracts is the stretching of the apple texture at the top. That orange looks really good. I kept looking back at your render when surfacing my orange, but it didn’t help.

cgpoint: I like the look of your render. The low res artefacts are giving it a textured look like a painting.

I think maybe there should be a separation of GI and non-GI. I think there was a concern earlier that there might not be enough people posting to do that. Doesn’t seem to be a problem now.

Jeremy: Ok, I did 2 more tests. I turned shadows on for all the lights and got this:

Now I normally work with 0-5% ambient intensity but with the above and earlier image I tried turning it up to 15% to brighten things up. Well since I was testing with more shadows I figured I might as well test with 0% ambient:

I’m not sure which I prefer. Hopefully fresh eyes can tell me what works and what doesn’t.

btw - this is fun.

#184

yes, definitely fun! :thumbsup:

i know, the bump map is not yet perfect, LOL… but im missing those typical small dark points inside the orange skin in most other’s renderings…

i forgot to specify that i rendered all images with a resolution of 3000 x2250 pixels. the EI render took relatively long because of the GI settings and the soft raytraced shadows.

as for your render, beeing picky, i’m missing a bit more of contrast in it. together with a general slightly blue/greenish color shift the rendering appears a bit ‘off’. the grapes do have a strange dark ‘aura’ around them, maybe a gradient put the wrong way? but yes, green grapes are really difficult to texture - i’m still not convinced by my own ones, LOL

cheers

holger, yout texturing is very nice! very convincing grapes material! only obvious remark: some of your grapes and cherries are still ‘levitating’ a bit.

looks like you like to play with the DOF in the middle of the scene. if this is intentional, maybe it could be pushed even further…

Zarathustra - I don’t know which I prefer of those two, maybe the 2nd, but both seem to be missing some of the shadows/occlusion you expect in areas like the plate right under the orange; it gets brighter right where you’d expect it to get darker.

3dworks: Ok, the resolution of the image makes the rendertime more plausible I suppose. You were right about the grapes. I have an incidence angle gradient on the translucency channel that I applied to the diffuse channel. I removed it from the diffuse and applied a slight procedural because even the green grapes have those blotchy, dull patches. I have to admit, the grapes took the longest to surface even though they don’t have any image maps. They just kept looking like olives more than grapes, but I didn’t want to give up and change them to red.

Jeremy: The orange isn’t sitting directly on the plate. I didn’t know if we could move anything. Light is getting under it.

I’ve always thought it’s harder to get that in-between light like in a lot of Pre-Raphealite paintings than say a Caravagio chiaroscuro, but then again everyone loves drama. Here’s a new render with more contrasts:

Hey thanks ppl glad you enjoyed the image…

…and Zarathustra… what serendipidy… that is the name of the computer I rendered this on!!

#190

hi,

thanks to all for your comments!

@AdamT: let´s look… maybe I find time to make a dramatic one :wink:
@3dworks: mh, the focus lies at the front of the plate … I´ll have a look…

Here another update.

for the fun, a quick 2nd take, lower key and more classical lighting. same textures. No AO this time which lacks a bit.

i tend to prefer the first even if it is a bit flatter by design

break out of the first scene :

…aka ‘cherries in the spotlight’ :slight_smile: - rendered in lightwave/ fprime. this challenge is too addictive, LOL

cheers

Hi guys,
I saw a coworker working on this challenge and thought it would be interesting to take a different approach. This is lit in shake using only a z pass and a bent normals pass. I created serveral macros to do diffuse lighting and shadows. Here is my progress so far.

The shadows are a little off because I’m generating them with just a z pass. I want to add specular highlights and try to do texture mapping in shake using a UV’s pass.

#194

Hello everyone, many great entrys on this!! Nice idea this lighting challenges:thumbsup:

Here is my try:
I wanted to make a “dense” light scenario, i’m not very happy with apple and the leaf, and the green olives on the botton are also a little greyish, but well, i kinda happy with the way it looks.

Maya & MentalRay, all textures are procedurals, 3 area lights and finalgather enabled. SSS on the fruits.
Defocus and Levels on Photoshop.

And here are the passes:

All 3 Lights & FG

Light 1

Light 2

Lookin good Markus. Some quick crits on the shading. The cherries and apple are a little too uniform for my tastes (yum cherries). I think both need a bit more of the specular broken-up.

Does fprime equate to a radiosity solution?

#196

It has the option of using radiosity or just normal lights.

#197

Good to know… :thumbsup:

#198

Okay, now have the Cherries break out in a dance-and-song number… !! “The cheese is alive, with the sound of cherriieeeeees”

#199

hi jason, nice to see you here - …agreed for the speculars… :slight_smile:

yes, fprime does a very fast and accurate radiosity (apparently using a variation of MLT).

For the sake of fun I tryed different settings:
