Simple Renderings Thread

Not true PureSpider,

All those renders made use of reinhard. You have alot more control over the scene with it i find, you just need to tweak the settings correctly.

[PureSpider]

May also very well be.
Tweaking the settings of Reinhard can also brighten up the pic alot.
I'm thinking of the Burn setting!
There once was a wiki page about that...

here we go, stock simple rgb emitters

Nice render indeed! I like the donut and especially its chocolate topping. And the cup texture is great. Just the handles need a little more love, it seems there is some space between the handle and the cup.

We need tonemapping cause indigo outputs images much more dynamic than any monitor could display. what might appear white on your screen will have some nice detalíls in the .igi, and what appears black is also calculated with much more precision internally. with reinhard we can tell indigo which part of the dynamic range we want to display. I'm sure somebody can put this more correct and technical, but this is how it works:

Pre-scale affects mid-tones and shadows. it is always set to 4, lowering it means darkening mid-tones and shadows without affecting bright ares that much.
Post-scale affects the bright tones. Moving it above the default setting brightens them, finally clipping them to white. This also affects nearby pixels, so setting it at 2 will probably turn all your brighter areas to white. (desired effect?)
Burn setting is weird though. In general: with a lowered pre-scale, setting burn actually near or lower than the pre-scale-setting, makes the image brighter with higher contrast. setting it higher makes the image darker, more grey and more "washed out". Surely someone can explain this better.
But it is actually quite easy to just play with the settings... good luck!

(posted two messages cause I got a weird error...)

just noticed I was probably wrong about the default values... which doesn't really matter as they're relative values as I understand them.
matsta: haha I found out that I have a render quite similar than yours!! reminds me that I wanted to try some skin but never did...

When you use studio lighting, what is your environment set to?

[matsta]

None, Mesh emitters, neo, you should try to use sunsky as little as possible when doing any sort of product shoot, unless it is actually outside.

[neo0.]

Well, see, that's the thing. Sketchup doesn't have a "none" option as far as I know. I might be doing this the wrong way, but what I usually end up doing is using the black background color. As a result, I get alot of black on my objects from reflections..

[PureSpider]

Hmmmm...
Wonder what type of refections you would get from "nothing" maybe black?

[zeitmeister]

This comes out like a die-cast-model... stunning toy look!

[matsta]

Um, build a studio that is basically a box, with wholes in it the shape you want your lights to be, then the background colour will only shine through the gaps were the mesh emits should be, should fake the effect quite well. find the elegant solution!

I've been fixing up blendigo for 2.0 and have become quite an accomplished modeller.
