Hey everyone,

I posted this shot in the Finished Works gallery also, but I wanted to make sure all you vfx enthusiasts got a look at it as well. I know sometimes I just stick to one area of the forum, myself. :) The shot is at:

http://www.robzeigler.com/work/compositing/

Animated in Maya, composited in Shake. There's also a breakdown of the elements provided.

The shot is locked off and I've moved on to other works in progress since, but I just wanted to share it with all of you, too. Any comments or feedback is welcome. Thanks!

very cool! The thing that caught my eye was the grass integration. It could use a person getting bitten in half though...

Very nice. However, you should probably add a little more bounce light coming from the ground. The T-Rex looks a little dark on it's belly and underside.

Hey Joshua. Thanks! I hope the grass integration caught your eye in a good way and not in a distracting way.

A person getting bitten in half would be great, but I think that may be stretching myself a bit thin...not sure if I have the resources for such an effect. ;)

PixelMagic,

Good observation. I'm aware of a Quicktime gamma issue between Shake and Final Cut Pro and I fear he may have gotten a bit darker in the transition between the two apps. Also, he was rendered out with Maya software, so on my next go at him I'm going to use Mental Ray and really focus on a quality render straight out of Maya, and then simple tweaks in Shake.

Good eye!

Hi Josh,

nice start. Please don't be too put of by my commnets as they are jsut my opinion !

A couple of pointers. I think the underside comment is well mentioned. Also his upper edge against the sky is too dark. If the light behind him where that strong I would expect to see soem rim or spill lighting on him. Also how does the shadow for your fg dinosaur relate to the shadow for the bg one ?!? I would expect more a defined shadow as well as a contact shadow. I also think that you need to push the spec more, maybe even bloom it a little. as for colours the fg trex is much greener than the bg, which is the ideal colour !?.

The lighting is a bit off for both trex's but it is especially so for your fg rex. We are seeing the wrong ares of him illuminated considering that the sun is behind both our charcters. Also the case with bg rex where the side of his head facing us is too bright considering it should be the 'shadow' side. The balck levels of the fg dino seem too dark also

Another thing you might try is adding some occlusion in the creases of your model.

Tahl,

Hi! My name is Rob, actually. There was a Josh who made some comments on the shot, though. :D

Let me start off by saying that I'm never put off by critiques. Your comments are right on, actually, Tahl! I admire your work so you taking the time to focus on areas of improvement for that shot are well received.

I think what it all comes down to is that he was rendered with some simple lighting setups in the Maya software renderer. Not to put it down, but after playing with some of Maya 7's Mental Ray settings and Render Layers, I can really see the benefits of more focus on specific shaders for spec and especially Ambient Occlusion.

I hope to be able to use this model for another shot soon and really get into the nuts and bolts of the renderer, because, after all, it's not going to be seamless if it's a poor render in the first place, right? :)

As far as ideal color: funny story on that, I'll give you the short version. He was originally much greener, but the paleontologists I was consulting were really no help in trying to give me pointers as to what color he was: they had no idea themselves! :) Richard Cheek, the modeler and texture artist of the rig had made him a slight tan, to which I tweaked in Shake. People who saw the rough comps didn't take well to the green, so he eventually got to be a more brownish color.

Rest assured I will take your comments into consideration and focus more on the shading, lighting and rendering for future T.rex shots.

Lastly: don't worry about putting people off. Constructive criticism is what makes these forums so great! I'm happy to be surrounded by people who have solid skills and experienced eyes who are willing to share their opinions. We have a great community. :)

Thanks again, Tahl!

cool.

sorry about getting your name wrong I was skimming threads while at work on Sunday and obviously not checking to close.

Thanks for saying nice things about my work. I feel like I have a loooong way to go myslef so I am never sure about giving crits. I would always recommend looking at great painters and photographers though because the same principles of colour and composition help make better shots !

I know from personal experience that the more opportunity one has to get feedback from other folks whilst developing shots the better they end up looking. I am always trying to get more people infront of my screen. A friend once told me that everytime you look at a shot you loose 10% of your objectivity. After 10 views you're over !

Tahl,

I agree. Once you get tired of looking at the same thing over and over, you really have no idea if it looks good or not. I enjoy critiques, personally. :) It's never a bad thing to hear someone else's opinion.
