stuck in progress

@CTZn: Thanks for the hint. I will check out if I can used said bug for my purposes

@galinette: I acutally had the same feeling concerning the under-exposed look of the last render, but didn't know what to do about it. I will try turning up the gain/exposure and see if that helps.

Thanks again to both of you, and a Happy New Year to everyone here at indigorenderer.com!

p.s.: below is the latest finished render from a new perspective -It only took about 48hours thanks to my new high-performance desktop

@galinette: sorry forgott about the albedo question: If you say max should be about 80%, then the albedo of the walls is actually still way to high! It's a diffuse material with rgb 0.925 0.925 0.925 .... But would it tend to look more grey than white if I turn it down to under 0.8? Or would I have to change some other material properties that I'm missing at the moment to still give it the impression of beeing true white?

All you'd have to do is increase the exposure to compensate. The rest of your materials will look a bit lighter because of the difference, but you can adjust for that by lowering their gamma a bit. White is essentially a really light grey, so if you bump down the level of your 'white', then you just have to increase the amount of light to compensate.

That's progress, how pleasing.

Talking about the environment map, it should be possible to get more of it without changing the ressource.

For the moment I just tried turning up the gain

That's the first step indeed. There is now sufficient light coming from the env, as verified by the linear/camera tonemapping.

Now, did this first step enhance shadows ? I don't think so, only relatively to the exposure level, not by increasing the discrepancy of the source's powers. At this point you could have nearly the same result with a white-ish background I think.

What is all this about ? Nothing, just an introductory movement: you may want to decrease the environment texture C parameter in order to set the black point muuuch darker. Eventually you will have to counter-balance the global energy loss by increasing the gain (B parameted) proportionally. Not: equally, as B is a multiplier and C a threshold for the lowest value; it sums to the B multiplied value, and actually the threshold must be set lower in order to bring burned out regions back in the middle levels. Then you will enjoy your map to a larger extent !

That's a bit of a circumvolutive explanation, hopefully it makes sense

PS: in fact it should be possible to compress the full dynamic range to the film capacity with only the B and C parameters. Rethorically speaking, as this would reduce again the range to about nothing.

@StopminTom:
I tried lowering the albedo of the walls even more, and of course you were totally right definitely looks better now, thanks for the explanation!

@CTZn:
Thanks for the in-depth explanation, I think I finally got the whole idea of changing the envmap parameters! I attached the latest render using the changed envmap. In a previous render I changed the parameters even more drastically, but then feel of the lightning was too much of a sunny day, so I went for a more subtle version.

Additionally I'm starting to sculpt several small items to put in the scene, following the advice of a soup in an earlier post. The red bottles are the first of these, next project is beamer which will take some more time modelling, but will follow soon. I'll keep you updated on the progress. Until then thanks for all suggestions and explanations, I appreciate it a lot!

Have a nice week, cheers!

[CTZn]

Some amazing details, I love it.

[dechrigi]

Thanks alot CTZn!

I the mean time I finally finished some other item to fill the room with some more life
Introducing... the BEAMER!

[StompinTom]

Coming along very nicely!

[dechrigi]

...finally managed to spend some time on trying something new: modeling a plant

@pibuz: thanks for the comment - of course your right, I uploaded a new version

[Pibuz]

...aren't these a little too dark?
