some testing [maybe kinda tutorial thread]...

scene from these tutorials

only made some materials and new camera

render settings

Lights 1

Lights 2

a64@2.7GHz

decent time for render, IMO. The white one is IR-LC with RGB=255 vray material for override mat

that black square in right corner of an image is a model error, double face, corrected later

next steps:

For faster render, rayserver should be tweaked a bit, like we've done in brazil on regular basis for final renders, rayserver initialization took a little more with more poly's but there was a good tradeoff and we got faster renders

In this particular scene, MaxTreeDepth should be raised (it's always a value higher then default), and looking at the manual, and testing in low res, with no GI and no AA, I've put 100 for MaxTreeDepth and Face/level coef = 0.2 i something else, I've made my bucket size larger. For that low res quick test, it took 47s to render. After all this litle tweaking, 37, and after bucket resizing - 22s!!!!!! (those seconds I'm only rememebering, but it should be ~ 2x faster)

Now, second version of the scene, a bit different mats, and it ended up pretty nice, off course, it can be better, but one must cros a line and make s stop so I don't loose too much free time on this (it took almost all day )

critiques are most welcome:

Some vRay FrameBuffer CM tweak:

so the image is saved and a bit edited i PS, diffuse glow and some sharpen

here is the scene

render time for 2000 pix is 2.5h, but on 2.7GHz DC opteron and lower AA at -1 1

Pure render i Pure render with VFB tweak

As for photoshop, I use something like this:

1. diffuseGlow, default F/B colors, values 0-1-7

2. I get in QuickMask mode and with large soft brush paint the central stuff in image, then out of QM mode, ctrl+shift+I and (Smart)Sharpen. When the image is resized, let's say at 800pix wide, then I let another sharpen cause I don't like blurry images.

and final stuff, just to try some more things... changed camera, night shot

pure render:

-----------------------------

a bit color correction in photoshop:

-----------------------------

a bit photoshop v2:

-----------------------------

[jonel]

cropped render, faked dof with z-depth pass as a filter mask (LensBlur):

-----------------------------

so z-depth from scanline min-1 max-6 (i think )

-----------------------------

then you paste in quickmask over render layer, make a mask, and from lens blur-a filter choose option for DepthMap Source - LayerMask

One can use the z-depth layer for more things, like if mask the render with z-depth pass and make a new layer bellow, full white color, and you get nice fog...

-----------------------------

off course, here is the scene (max 7.5)

no comments, even for renders?

Very good study.

The renderings are pretty nice and the whole research is very useful.

Thank you!!!

Keep on!
