View Full Version : realistic bottle

04-12-2011, 06:16 AM
Hi there!
I have bottle to do. I have photos and my render. And still my work looks very artificial.. any idea what improve my render? Of course water drops on bottle are not necessary. We talking only about glass. I know, on the internet are many tutorial about glass, I read most of them, but maybe I do it wrong? And it is possible without "note"?

IŽd say that a good HDRI reflection would help.

This might help:

Well, what particularly don't you think works?

(I wish I could make something that realistic.)

Well, the glass isn't perfect. Looks e.. foggy? Fuzziness..

As long as I watch on the compared photo I see details which can improve may render. I.e. bottom of the glass, on my render is almost missing. Probably word "TYMBARK" on the bottle neck - if will be not from bump will looks more realistic - but I don't know how do this..

Builtdown: where I should put the HDRI bitmap? In the "Backdrop options" or maybe "Surface editor"? Shame to say, but I never used HDRI in Surface editor/enviroment.. Could You help me? In the meanwhile I will try this way with node.

Quick tip, put your diffuse down a bit and reflections up (or put the diffuse very low and reflections high), also your reflection map needs to be HI-RES/sharp/HDR prefer and change refraction index.
Experiment with fresnel and incidence (gradients) for transparency and reflection.
If you quit making glass with standard node setup, experiment with dielectric node.

I used Image World with the Kitchen Probe HDR-image for this image :

Hey Bracki, how is your bottle developing?

Thank you for your interest :)
Well, not so good, but not so bad too:) Despite the views tutorial, dosn't works with node.. I don't know why. Traditional ways gives better results for me, maybe not so fast as a node, but lokks better.
Gennerally looks nice, but I am aware of some shortcomings. But most of them (like thickness of the sidewalls) its on the modeler level. Still don't know how else can I get the bump effect with the "TYMBARK" word, ofcourse, without bump :)

I would model the logo text and not use bump.

But how?

If the bottle isnt' a SubD object, you can try the Drill function and do a bevel on top of that result.

If it is SubD object you could use the bump map as a displacement map.

Sorry, I wrote in wrong thread:)
I make another.
