This course contains a little bit of everything with modeling, UVing, texturing and dynamics in Maya, as well as compositing multilayered EXR's in Photoshop.

My biggest beef with this right now is that I'm not seeing any shadows, I'm having a hard time telling if the board is touching the marble surface.

I did some minor changes to the materials, used a sky image for IBL and decreased the margin between the board, the table and the figures.
Render time is now 1h 4m and I was using Photoshop in the same time so it's much better.

the shadows are there. the figures are transparent so they are pretty soft. How can I boost their intensity?

C&C please,
Benny

Could you do a render with just lamberts, shadows and lighting, as I'm not too sure whats going on.

Lambert render:
user added imageuser added image

My lighting setup:
Key light - Spotlight 1,1,0.8 RGB, linear decay, 130 intensity,
Raytrace shadows, 0.3 light radius, 5 shadow rays, 3 ray depth limit.

Fill light - Spotlight 0.9,0.967,1 RGB, no decay, 0.35 intensity,
no shadows.

Back light - Spotlight white color, no decay, 0.25 intensity,
no shadows.

I've got another directional light to light the background alone.

@Genny - this wasn't a test render. It was a high quality render and quite an improvement for the 2h 18m...

when I say lambert I mean just add the default lambert1 to everything, then you can evaluate whats going on.

The directional you have for the background, is that for the HDR?

Oo... Doing another render right now so I'll do that lambert test tomorrow I guess.
The directional is for the bricks in the background. it is linked only to them through the light linker.

Thanks for the support guys (and girls user added image ) :bow:
I guess I'll be moving to another project soon...

I don't know if its the HDRI doing it, but something is making it look overexposed, I especially see it on the translucent pieces. Could I see a screen grab of the workspace?

Honestly, I think its happening because you're using an HDRI along with so many lights.

my guess is alongside with the hdri lighting, then the other lighting. and asuming you have raytracing. Ye that i`ll explain the rendering time.

I would suggest as for any other project your doing, start with one main light, then add more lights. This way you see what happens for every light and also the render time.

Also because your objects are glass, the refractions are also heavy for rendering.

So now in general you gotha start thinking, ok what is my final image going to be, a close up? Just from far in full?

For these objects i think you can get good results without using hdri lighting, you would get a good result using a dome.

So if its far try to reduce the refractions to 1
if its close try starting from 1 then upwards.
Also try to see the difference between shadowmaps and raytracing.

Try to switch off GI and FG

So the important thing of working is knowing what you want in the end. And doing the renders step by step.

Anyways thats what i have learned, and helps me get nice results user added image

Another Lambert render:

Got rid of the IBL and placed a NURBs sky dome instead:

I'm not sure how I'm supposed to do these things so please tell me if you think there's something wrong with it.

I'll make a test render soon and if I like the result I'll make another 1600X1200 overnight.

Sorry for posting only now... I had a contest all day yesterday.
My prize for it is a stretched(I don't know how to express it in English) ligament in my elbow because some bastard couldn't put his ego aside, and my elbow went past the 180 degrees on a hand bar user added image :angery: :headbang:
