Hi, I need help with V-ray glass material for 3ds Max

[Anonymous]

Hi, I have been searching for different V-ray glass presets for 3ds Max, found a few different ones but I just can't seem the get my glass to look the way I want it, Could someone please help me with setting up the material and settings, I do have a reference image of how I want it to look, (http://www.3drivers.com/catalog/336/11896/) Any help will be much appreciated, Thanks:)

Hi,

Your Link is not showing a particular image.

In general glass is one of the easiest shaders to make and one of the most difficult to build a scene for.
At least a studio kind of scene.

Use a Vray Mtl. set refraction to pure white and IOR to 1.44.
Than raise the reflection to something around 180*180*180.
Play with the fog color/multiplier to make it colored if need be.

If you have your scene done.
Play a bit with reflection color and refraction/reflection deph.
Also you may also want to enable backside reflection.

If you want to add caustics I would recoment to watch this tutorial:

Good day Ihno, thanks so much for replying so soon,

Will try your settings as soon as I get home,
I have been looking into caustics recently and how I bounces in water and creates those light effects but I just can't get my glass to look anything like those reference images,

Could you please help me get it to look like this

in one render and like this http://www.3drivers.com/upload/iblock/d99/aqua_03.jpg
In another render,

Perhaps with a basic scene, any settings that work would do, I don't mind the render time,

Thanks:)

Your references look like they use hdri Lighting and environment. Here is a tutorial for that:

With hdri you'll be able to quickly get something to be reflected/refracted.

But you'll have to stuck at whatever you find on the internet.
Free hdri's are often in a quite low resolution.
Also hdri's are not the best thing to simulate interior lighting.
But its a good starting point.

I haven't tried that as yet, I will try it out now, though in the one image the glass is transparent and in the other it was a slight yellow tint, would that be from a v-ray sun? Or exit or fog color?

[Ihno]

I think it's just another hdri with a more yellow lighting.
Or a camera angle which shows a more yellow part of the hdri.

Don't pass over davidveyhle's post. These tutorials are great.

Hdri gets you a quick scene setup but to get a realy good result (I dont like your Reference pics ;-)) you'll have to build a scene.

It's all about the scene.
Unless you are trying to make colored glass for something like beer bottles the fog color is the last thing to touch, just to get the last 5% of the realism.

Great will try that, what settings would you recommend? Also the setting of a V-ray camera and lighting?

I'm really not sure how to set that up

[Ihno]

Follow the tutorials for the scene setup.

The exposure settings:
Set it up like you would do in a real situration.

I like to setup my exposure first. And than light the scene.
After the scene is done I come back to it and just slightly edit the exposure settings to cach the magic 😉
That workflow prevents you from creating blownout lightsources which can lead to problems.
But you have to know what real camera setting would be working in the situration you are trying to shoot.

I would recoment to everyone who starts with 3d lighting to get a DSLR and practice realworld photography.

But there are some information about it on the internet that can help:
