Just throwing in my First WIP. Just my first pass at getting my materials and comp together. Still needs tons of texture and lighting work. Im enjoying this one

Thumbs up

prestonplatt, ArthurStaschyk

Great results so far!! Keep going!!

Giorgio, that's amazing theme, I love the concept and it's pretty inspiring. I hope I'll get something to post here soon. Will you add your version too?

ScallyFox Thanks I cant wait to see what you come up with!

ArthurStaschyk Looks awesome! Only thing I could point out is that vase/Glass at the back could use a little more love.

This is my Second WIP Its getting much closer just adding more details to make it more organic and living. Still exploring. I remodeled some of the pies. Loving this challenge already learned alot about my Vray materials that I didnt know about. This is straight out of Maya

@ArthurStaschyk Great image ! I will add a bit of blue to the lower part of the image and boost a bit the caustics. Also add a bit of dirt to the ashtray (not the ash, that are perfect, just the ashtray) and define a bit more the left part of it (in the reference you can see a bit of caustics also there). I would also change a bit the texture of the box on the left (less bump and probably add a few writings). Really a terrific job !
@FranciscoSCN thanks for the link ! really interesting
@ Preston. Great start and also improvement from first image. I dont' understand what is the the left gray (chair?) on the background. It contrast a lot with the other colors in the image and I find it a bit distracting.
The sugar container seems to float (probably no occlusion ? look in comparison the salt box) The material of the ketchup bottle is great. I would give a bit more of space to it in the image (and also to the spoon) Overall, I will add a bit of dirt/noise to all the metal surgaces that now look too polished. The shader of the mug is great ! I will work a bit on the coffee (add some SSS in last pass probably)
About lighting I would add more contrast in the image. Now it look a bit flat
@ashes2bones Good Start ! I would change the shader of the cup in front of the image. Since it is too similar to the wood of the table and also a bit irrealistic. Add dirt and scratch to the metal to make it more realistic. Also add samples to the glass that now seems a bit too dark. Also contrast more the image. Chose a light source and give nice shadows to the opposite part.

Here an update on the image:




I focused on some caustics mostly and doing a new glass. Also finally some dirtiness on the ground of the ashtray and some work other stuff too. Next will be the cigar box on the left, and maybe some other caustic pattern... atm the glass looks kind of "hectic" and maybe to detailed I think :/

@jojo1975 Thanks for the hints, I also have similar feeling about the most stuff

@prestonplatt Yes, I'm also not very happy with that glass bottle in the back :/
I tried modeling a glass decanter, but the look of my "diamond curl" surface wasn't really a gain for the scene... it already took long enough to spice that glass up, lets see if I find the mood for another try on it.
BTW nice skateboard in the background :P
You scene looks great btw. maybe the metal looks to perfect shiny, most are more dull. A little bit of "action" on the outer coffee surface would be nice i suggest, something like that

@ashes2bones is that also rendered in Indigo?!

Caustics

@FeD: I struggled with the caustics too, the main problem was that each light I created and caused some caustics was lighting up the scene in a unwanted way... So I tricked the Render Engine by using the "laser Pointer approach" ^^
I created a narrow IES file that was aiming at the glass, it generated great caustics and only lights up the scene with the caustics and interesting reflections. Also some bumpyness in the glass and whiskey causes more interesting caustic paterns

I attached the IES file I used, its not perfectly thin line of light, but that caused way to sharp caustics for my taste.

ok no C&C ..no problem......
but here is next update from me...

 
Old 11 November 2012   #28
Hi Guys. Have to say I'm a little nervous posting here for my first time as I know this site generates a very high standard of work. I'm relatively inexperienced with Maya and have only attempted modelling in the past. This is my first attempt and texturing and lighting a scene manually by myself and I realise it needs alot of work to get it up to scratch. However I believe these challenges are going to be a great way for me to learn and improve my skills if I can get some constructive feedback my posts. Any constructive criticism will be taken on board and not just ignored, really appreciate any help I can get.

Thanks, Will.

Another small update
The development steps get smaller and I focus more into detail, again the 80/20 rule strikes here.
I changes the icecubes to a little rougher surface and also the decorative cuts of the glass get some tiny little roughness too. By that the glass becomes less chaotic regarding the reflections.





@ WilliamJames: There is no shame in being a beginner, everybody was one once
I also did a lot of challenges here, since years, but that here is the first I participate in public.
A good start you have there, but somehow the overall look seems so "painted", I don't know much about Maya, but I can tell that the red bottle on the left seems quite oversaturated and the glass next to it seem to brighten up the background somehow
I would start to focus on the wood material of the table since you can get a lot of rewarding realism doing that probably, by a fitting bump map and some map controlled reflections.

@ ndosanjh: The noise is because I use a raytracer for rendering and Indigo does create a cleaner image the longer it renders (like Maxwell or Fryrendere etc.). It was late and I simply wanted to go to bed instead of waiting further
Check the fluid in you bottle, seems like it interacts with the glass and creates some poly artifacts, also the bump on the table looks way to high for a varnished table.
