The Brand X bottle doesn't cast much of a shadow, but there's some kind of shadow to the lower right of it that comes from nowhere. The Leet bottle has a lot of black in it, where I'd expect bounce light on the lower surfaces and some extra environment in the refraction.


Thanks Jeremy for your comments..
I am using XSI and mental ray to render.

Alright, here is my second try . I ve tried to fix the shadows, and managed to increase caustics effects.

Actually I would like to put some reflections on the bottles. But first, I will try the basic reflection and if I can find time, I will try to use HDR images..

And as far as I ve seen, there are some low res shadows and the brandx bottle is not good as I want.

As always, C&C s are welcome.

Hey again.
Here's my second attempt:

I couldn't get any lightbleeding to work so I went for a blurry reflective surface instead.

Actually the graininess is mostly from the DGS material. It'll go away when I further increase the samples. But where can I get this lens shader you al_DOF_lens_plus shader from?

The site where the models are hosted must be down, I get a timeout when trying to get to it.

Can someone look into this, I was hoping to participate in this one.

AndrewMarch - It's up and running now if you can try again.

Thanks to mesutcapkin there's now a Cinema 4D version as well.

pap87 - That's a nice image. I wish you could favor the Leet more, maybe the Leet casts the bright blue caustics and the Brand X casts only a dark shadow? Something should make it clear that Leet is the better one, the focus and size in frame are a good start but I think something in the lighting could indicate the preference as well. Feel free to change whatever you want about the scene in order to get your point across.

madmar - Especially if you are using XSI, I think you could get nicer caustics from the Leet bottle, and soften the shadows. Maybe the label doesn't need to cast shadows or at least not block the light so much. I think the label texture isn't mapped accurately to the Leet label, the white border doesn't seem to be a consistent width all the way through.

Kain-Hazem - Welcome. That's a good quality render. Maybe you can keep working and add caustics, and think about other ways to show that Leet is better than Brand X.

DarkNemos - Nice image. The bottles appear to be floating above the ground. I like the metalic look, but it seems strange that the top of the bottle right above the fluid levels is metalic, then the rest is plastic?

MinaRagaie - That's a nice image. Bright rim/kick lights are no necessarily a bad thing, if they are a part of how you are highlighting the product. Keep going with your concept.

Thanks for the feedback; here's my second image.

  • Added bounce lights on both bottle caps. It might be too bright on the Leet bottle but I think it looks OK.
  • Added caustics.
  • Moved BrandX bottle slightly away from Leet to get rid of a weird tangent and also to expose the edge of the reflection of the backing in the bottle to make it less confusing.
  • Some blur in the refraction.
  • DOF to put BrandX subtly out of focus.
  • Cheated index of refraction of the leet liquid to make the image of the BrandX bottle less bizarre.
  • Texture changes to BrandX liquid and plastic to make it also less weirdly CG blurry.

Here is my first setup on this one, still have to smooth out some geometry and fine tune the overall image before the final render.
3 lights used and no post.
C&C and suggestions are welcome!
Cheers everyone!

Hello all,

I'm a newbie poster in this forum, so please don't be gentle. This is what I got done within my lunch hour. Currently playing around with the lighting before I figure out the best way to display the product. So, anywho tell me what ya'll thinks.

Second try .. Experimenting with DoF on this one also some color correction and glow added in After Effects..

@Jeremy.. Thx for ur comments im trieng to work out the caustics pass i need to use Mr for that one and composite back .. hope u like the updates

There's no Lightwave file to download. :(

Great entries so far though.

The OBJ file worked well enough in Lightwave for me...

Trial 2

I need to losing the brightness of the Kicker light on the side. But I like the stage set up. Any other advice for the lighting? Could I add lights? Lose lights? Add a certain color tone? Etc...

Raven Eye

I don't get what's happening in your scene? lol, is the Bottle hanging it'self and the other bottles just watching it happen in the distance, or did it get kicked into the screen by the other bottle?

Right now, I'm playing with the composition before I do my add on's. Kinda play with the scene until insperation hits me sort of thing. The inspiration that hit me is to place leet in a soap bubble floating in air. While brand X is left laying there on the ground. Going to try to place a pretty ladies reflection in the bubble.

But, since you mentioned hanging. I can alway put a noose on Brand X and hand him high. I would have leet wearing a white cowboy hat.

I thought about putting a knoose in Brand X. I started it too and thought, nah. I went for the door slammed in the face ahaha. DO THE KNOOSE RAVEN EYE. I hear ya. It's hard to come up with an idea right off the bat. At least for me. Especially after you look at some of the ideas that were taking before you got the chance to do it. lol First come first serve I guess. haha

Oh, you can do the noose idea. I don't have a model of a noose or a cowboy hat nor do I want to model those items. Modeling bubbles and bathroom tile is soo much easier.
