mental ray topics :-)

[rajasekharan]

hi , i wanted to explore mentalray a lot . posting this in a belief that people will help me get to this wonderful render . please cover mental ray lights , materials , HDRI. saurav . . please help

[gxsaurav]

Well....first of all, go to cgtalk.com for mental ray or evermotion.org for Vray tutorials & basics

Mental ray depends compleately on the dimensions you use to make your scene, like i use centimters in the viewport & system of 3Ds Max, however, if u don't like i did ones, my scene was actully 15km in length, & photons were not showing at all. So first, make it a habit to model in correct dimensions. they should really bundle an optical physics book with mental ray

2nd, start with basic lights....I use the 3 point light setup, one key light, one fill light, & back light...

3rd, i will post tomorrow, right now going to sleep

. . . . ok mate i am waiting for tut tomorrow . dont fail
__________
help me here please

[gxsaurav]

Sorry, was away

rajasekharan, you do one thing. Since there are two types of rednering & I m not familier with Maya anymore, i m telling u the method, you try that in your scenes, & see for yourself how it works. Use Maya 8 or 8.5 as they have Mray 3.5. I can tell u exectly everything in 3ds Max but not maya. You are better off visiting some threads on cgtalk.com for maya

1) Exterior scene

1 key light, mr area spot. This is the main shadow casting light, just apply this with no FG & GI, & position it according to the Shadow direction you want

Now, add one skylight to it, the normal one in maya, enable FG & go with draft profile with 2 FG bounce, render it...show it here, how it renders

[rajasekharan]

hey , thanks for it . . i am half way through with maya . been swinging between max and maya . the thing is how to fake a sky light in maya . i dont see a sky light there .
__________
well i use 3 point light , thats ok . . but did you look at the gnomon videos . the way they have done SSS thats what i fail to get . and ofcourse the HDRI effect that vray gives me . i cant replicate it in mental ray

[gxsaurav]

Well, i can tell u about max but no exp in maya now.

In 3ds max we have a "skylight", which u can create using create light control panel. Or u can use the mental ray 3.5 mr sky & mr sun, these should be in Maya too. There should be a skylight in maya too...check somewhere

I didn't see the gnomon videos....was not able to download them...do u have it?well, can u courier me the mental ray lightning & rendering dvd is possible?

to use SSS with mental ray, i simply use the SSS materials already given, add a key light & then modify the materials. It works mostly, confession : I suck in charectar modeling

[rajasekharan]

you want some . . . i have 4dvds of tute collected in my home . i will give you this month end when i go home . i have 4 gnomon cds with me . ripped ones . i have compiled to a dvd . will send you tomorrow eve or max by monday if you give me your address .
__________
do you have any tute with you . i can send all my video tute to you less than 10 dvd i guess . i need lighting tutees . i am more interested in materials and lighting stuffs animation is not my thing . i suck there . modeling , well i am trying and is progressing well . now doing all with edge extrude .
