Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

B&W rendering

is there a way to render out the images in B&W so i don't have to do them post batch render?

Hi,

there may be a more technical solution, but you could simply use desaturated textures and non-coloured lights. It's not a physically accurate solution though, as obviously real world black and white photography still captures objects which have colour.

I think you were better of doing it in post tbh,

cheers

You can use the photographic exposure lens shader, it has a saturation attribute.

It's in the "Lens" section of the Mental Ray nodes. Pop open Hypershade, can't miss it.

put it in the lenses shader slot under mental ray in the camera attributes.


From a readers' Q and A column in TV GUIDE: "If we get involved in a nuclear war, would the electromagnetic pulses from exploding bombs damage my videotapes?"

Sorry for hijacking the thread but can someone explain what the top attribute "cm 2 factor" does in this lens shader?

From the documentation: "In photographic mode (a non-zero film speed) this is the factor used to convert between pixel values and candela per square meter. In arbitrary mode (a zero film speed), this factor is a multiplier applied when scaling rendered pixel values to screen pixels. This is analogous to the Gain parameter of the mia_exposure_simple shader."


Imagination is more important than knowledge.
