Hi, just starting testing RC3... Frosty glass is here!! :D

This are actually 10 renders, 30 seconds each (5 min), blended together in PS... it's a good way to get rid of fireflies and reduces noise too

If you Gaussian blur some passes in Photoshop, you might get better results with fewer passes?

hahaha, I remember once user gk pulled out an animation with the demo and by only using his right hand :D he was proclamed a hero...

nah, it's not that much work, specially with a max plugin that automates the whole thing (conviniently programmed by gk himself). Then there are Photoshop actions to automate the blending.

Gaussian blur on one of the layers would ruin the whole thing. You still want sharp edges and stuff.

edit: since downsampling is a great antidote versus fireflies too, I tried a new test: 2 renders, 4 minutes each, blended and downsampled by half... The little square is an overlay of a single 10 minute render downsampled, so you can see the real difference in quality between one render and two render blend. This basically becomes useful here just because there are massive amounts of fireflies being generated with this kind of material, so manual removal is not an option...

nice and cold!
I like the material, but on top of that I like much more that method of overlaying low sampling renders, I'll try it on some specular heavy scenes I had problems with.
Thanks

Since the new additions I'm material hungry, I've been testing, but nothing good yet.

The material it's just as radiance said, a regular glass with a turbulence on the bump channel... attached the settings, nothing special really, it's a balance between bump power and scale.

For the blending, I have tried many different techniques, the one I am most satisfied is setting all the layers' blending to darken, it slightly darkens the whole render, but veeery little

PS: underwear?

it's nice to see people using the procedurals to make other features by themselves that are not implemented yet (eg a glossy transmitter)
we've got some nice ideas about the nodes system in upcoming releases, so i suggest people try to learn how to use them as they will become very powerfull later on.

Nice setup, I guess now I'll have to model something to suit it, besides with the summer already here, a winter theme will be welcomed!!!
The heat also explains my sense (or lack) of humor.... kind of.... hehehe ;)
