These are all looking excellent. I'd love to have a crack, but I don't have the time at the moment...

Really interesting to see the direction everyone is going in.

@ Fused - thanks for the pointer -- I did look at that before, but removing the windows seems to alter the mood of the shot quite a lot, I get like a very sterile light from the HDRI that I am using. I'll change to Sun/Sky and see what that does.
Sun/Sky will do nothing. Keep EXR in env. slot, remove that glass (its not visible and is producing dispersion all over your scene).
For curtains use diffuse transmitter and place exitportals to windows. Note that EPs needs to be used with MLT.
PT + ET + EXR cant properly show soft lights and shadows from EXR file. It can, but without EPs.

Avoid bright white in scene (my persnoal limit for white is 218)
I can advice you to use agfapan 100cd camera. Its most neutral looking.

Screen on apple pc should be glossy, in real, there is glass. Your seems to be diffuse mat.

Try to rotate floor by 90degree

Thanks for the heads-up.

However, using EP-HDRI-MLT, as suggested, scene is much slower. Has dropped from 375K+ to 218K.

Also to add that making the Mac a matte screen was deliberate.

Ok guys, I keep on posting my tests..
I improved a little the scene with small detailing, and changed things on the left part, still not completely satisfied though.. I guess I'm going to try the mirror table on the background to replace the pouff in the foregroung, I think little reflections are due there.. Also, I need some lightsource on the right, and maybe an arch lamp for the concrete table...

By the way, here are my last tests.. Both rendered for 14h on a quad core machine 4500pixles wide, no GPU acceleration (BiDir+MLT). Resized and minor PS for both.

Pibuz, you are frightening everyone with your awesome updates !

In the future we will put the WIP subforum to contribution, that was never explicit.

Remember that there will be several winners. Beginners should take advantage of the challenge to learn faster.

Oh God... I asked before just to prevent that from happening! I keep posting WIPs to get some tips from you ALL guys, and of course if there's some tips I can share I'd be happy to.

There's nothing wrong with what you are doing Pibuz, I am used to proceed like so. Do I want to see more wips !

I'll keep my hints for them d:

edit: to all: check the first post for the rules and prizes.

Speaking of which, is there a minimum image resolution for the final image?

Your images are looking awesome Pibuz! Nice.

I found some time to have a play with this competition. Nowhere near up to the quality of you lot, but I'll post a WIP here soon...

Here it is: I went in a different direction, no shiny rooms of beauty for me :lol:

Theres a fair bit wrong with I know, but I'm doing it quickly between other work. The ivy looks wrong, need to fiddle with that. And I suppose the floor shouldn't really be shiny. Also its illogical that the place is derelict and full of graffiti yet the chandeliers are still hanging.....but HEY! Its all a bit of fun.

Ehi boss! Great atmosphere you have! Maybe something more..foggy would help, godrays from the openings and romantic stuff like that ;) Musk on the floor is really nice too! the only thing I'd change is the tone of the base color, I feel like a blueish one would somehow fit better..

I really like the graffiti! What is your technique to apply them?

(and obviously THANKS to zeit)

Heh, I'm not entirely sure how to do godrays, nice idea though. I tried turning fog on in sketchup which killed render time and hid the lights entirely....Might be worth having a play though. Graffiti is just photos set as a texture in sketchup, nice and easy :)

One problem I have is if I use freehand draw to do wobbly lines (as I've done to separate say brick and old paintwork) then it tends to do horrible things to any displacement on adjacent materials.
