Hi folks!
Here's another wip, to be completed!

The render time is huge, but only 'cos i let it cook the whole weekend in my office's pc: it reached something like 13000 samples per pixel.
But still here and there i see some fireflies, most of all in the area interested by the influence of the glass (also in the reflective areas, if you take a look to the road..). I realized i used a perfect white in the scene: perhaps it has something to deal with this issue?

for the windows and for the copper in general, i tried to create a blend material, to simulate the uneven effect of consumption, but i'm not so happy, seen the result. Still working on it.
This is the mat preview.

Looks like a good start! Whenever I do big outdoor scenes, the fireflies never clear up at the windows.

which tracing method are you using?
also, I think if you had the sun behind the camera, so the faces would be lit, you would see the copper better, just a thought.

Is that a big image you put in the background?

Hi crojack!
I think it's a BiDir Path Tracing (don't remember very well), but i know i've increased to 1200 the MNCR.
...

...Now that you make me think about it, perhaps you're right about the sun being behind the camera, but unfortunately the building's is oriented to the North so this image won't come out much different from this..

But in the others, copper should render full-power! We'll see

In the background: i've put a cilindrical pano image i found on the net just to simulate an environment (to get something in the reflective materials); then i would crop it in postpro and substitute it with the correct (but not panoramic) background..

thanks for your comment!

Interesting project Pibuz.
I like the appearance of the windows and that overdimensioned clock is a cool arch detail.
Curious to see the final render of this one.

In the mean time, I'll share a render I did (the house model is from the new charette at Vizdepot) using instancing in Skindigo for the vegetation:

Cheers,

Pibuz:
pity about the fireflies in the last render, probably due to some kind of bug in Indigo. If you can reproduce the fireflies in a much simpler scene, then I could try and debug them.
Your render has very little contrast (due to outdoors and high albedo materials I think), perhaps try using camera tonemapping or linear instead of Reinhard.

Kwistenbiebel:
Great render!
Can you please upload some of your fantastic renders to the Indigo gallery?
thanks!

both great renders!

omg, kwisten! If the repetition wasn't that obvious (those bushes with flowers and the leaves around them are *very* obvious), it would seriously look like a photo! Very well done

..kwisten: you have to explain me a pair of things.

There MUST be a kind of trick you have to get your images seem SO real! What's the trick? I really want to know! Is there some peculiar mat setting? Is there a trick in the postpro phase? What the hell is it!!!!!!!
I've tried also throwing an afternoon away trying to set a mat to its best, but my results are never THIS real. You use indigo, I use Indigo; you use SU, and I use sketchup. I really want a tutorial by you. It's a must. You owe us one. Remember it.

Second thing: how damn can you map a leaf?

Hi Pibuz,

I am not sure what you mean by using tricks.
The Violet tonemapper sure helps me a lot to make the appearance of the Raw rendering better. Also, I use photoshop to level out and balance the light a bit more.

Mapping leaves is really difficult in Sketchup. You can use the 'project' texture for that (= project a texture by paint bucketing it from a surface to the object). Luckily, sketchup can hold texture uv-mappings when importing .3ds ready-made 3d vegetation models , which is a big help.

I posted a night version of this scene in the finished works section.

cheers,
Kwistenbiebel

...) i attach another couple of test.
Tell me your opinions!

Wow Pibuz.....you do not need a tutorial imho.

These look fabulous

Only a day? You've been a member since December!

I have started updating the tuts but I am so busy that it may be months before they get released (even though the changes are small).

Welcome to Indigo jenujacob!

yea i joined since december.. i used to lurk and drool over the image gallery!

but never got a chance to download and play... then i saw the new release and the new exporter.. and thought it was much time overdue to play with this!
and whaaat.. u ve done an excellent job in the exporter.. i hope u were busy finishing of that subdivion tool for SU!
