HDR Glass tut and 3 Point light tut
I failed in the end with the glass tut...I couldnt get the lighting right...I will redo this glaas one at some stage...interesting stuff.
As for the lighting tut...wow...I did learn a hell of a lot in a short time Nilla. It certainly can make a difference between model > bloody good model! I recomend both of these tuts to the raw cadets out there. Guys it will make a diffrence and give your models a much better presentation. Obviously there are many things to learn but both of these tuts will actually make you appreciate your own work so much more.
Thank you again Nilla.
cheers bullet
Edit : I will be doing the glass one again at some stage...Im not happy with my effort.

It bleeds like water because you need to turn the color gain of the IBL down.Are you sure that second render is three point lighting? Because it looks like IBL to me as well, it's got those very distinct patches on the floor plane that comes from not having the final gather settings high enough with certain probes.
But not to worry, a week from now I will have nagged you enough for there to be a perfect glass render instead

When you open a new scene in Maya the render settings will be at default but when you open someone else's scene the render settings they have will carry over. In this case the model ctbram uploaded had final gather turned on, so when bullet added his three lights the scene rendered with fg and instead of taking a few seconds it had to calculate all the fg points which took about 40 seconds instead. So a good idea is always to check the render settings when you light someone else's scenes.
Also the reason for the extreme hotspot on top of the can was caused by a spot light with an intensity of 8 without decay which caused the overillumination, this is why I thought bullet was using some sort of strange HDR probe.

sigh.....
sigh again..this is so frustrating not having the time to put into my work, I shall be a noob forever at this rate! Anyone want to offload a nano particle of skill to me would be nice...I feel the twang of abandonment of Maya a lot lately.

...You should be using the mia_material_x for this, switch materials and you'll see a huge improvement straight away.
Agreed. The blinn doesn't have BRDF qualities so you'll have a surface that is equally reflective regardless of the viewing angle (unless you get a sampler info node involved)
Lol these smilies are awesome.

I included a part on the blinn shader and rendering glass in maya software to be able to go through the fresnel effect and how a glass shader is constructed instead of going straight for mental ray. So that shader there should have a sampler info node and ramps it must be the mapped reflections and ibl. You can't really beat mia_material_x though, I was on a mission a while back to see how well I could get glass in maya software with blinn and no indirect illumination and it's impossible to get blinn glass that comes anywhere close to mental ray shaders. Dave was lighting a similar scene in maxwell at the time and laughing like crazy at me
I like your blog btw Genny, it's very clever.

Lol I tried that as well, guess I'm a sucker for punishment. The mia_mat is a swiss army knife or sorts, I know I never looked back.

Ok I have stuffed around with all the settings again...aaarrrrr...yes it WAS a material_x but my settings had to be really tweaked...is there a reset to default???? for the render settings...I shall look.
Here we go...Im going back to the Spitfire now...this has had me buggered for a few days....I HATE software that carries over settings etc etc WITHOUT being told to do so. I have to deal with that crap ALL the time as a Surveyor and nothing gets me madder than a machine that reboots and comes out in feet and inches and Northing, Easting instead of Easting , Northing etc while you have a Supervisors tapping his toes ready to yell at you (not thats a worry Im pretty big LOL).
