Indigo Renderer Forum

Inspired by inject, allthough, its nowhere near as good.

Using exr lighting.. I'de appreciate any advice on making it look more realistic..

Don't make the tube holder THAT reflective...
Maybe a lower exponent will do!
And put it to the ground
Then, let it cook longer and we will see where that will take us

Hey Neo, thats looking like a good start.. Got a couple of suggestions for you.
1 ) the shelf of the test tube holder, make a second shelf like that and place it below the first.. So you have two sets of holes for each test tube, it will stop the tubes from sliding out of the holder.

2) have the tubes resting on the bottom, at the moment they are floating in the holder, test tubes usually have straight sides so the would slip all the way in until the are touching the bottom

Oh and one last suggestion, maybe put a small mesh light in the scene ( you will have to try and match the poser with your exr), see if you can get some caustics, but thats more a personal preference

Ior of glass is ~1.5... That should be the correct reflectivity.
Exponent should be pretty high, as otherwise the liquid will get blurry or the glass itself will even look like sanded...
(Or you use a Specular, where you always have perfect reflections)

Specular and exponent, since when?? Otherwise how to get transparent phong?

Huh?
You can use exponent for glossy transparent... that is "transparent phong"

Looks good!

To get the scale to look right, you also might want to consider adding a meniscus to the contents of the test tubes.

New versoin, a bit of post pro in violet

Quite good, the image lacks a bit of contrast imo (medium tones too bright). A meniscus is the deformation of the water surface around the tube.

Hey neo, why is everything always floating in your renders?

it doesn't hurt anything if surfaces are touching in sketchup/skindigo/indigo.

looking better though!

could use some sort of context, a desk or some sort of background or something.

Any idea how I could fix the issue w/the midtones?

Personally, my issue is that the glass looks too plasticy...

Different tone mapping and/or different environment map

Well now I'm seeing you image in a daylight situation and contrast is not really an issue, some times I'm a bit picky
