Lighting preset beta version

Hi all,

Finally here is my python script "Lighting Preset", it allows you to create presets for your lighting ( All lights, cameras and rendering parameters ), save it to a .xml file, load and share easily from a UI in maya !
Works with maya 2011 - 2012 - 2013

 Version in beta, free for download here :

LIGHTING PRESET beta0.4.0

________________________________________________________________________

To use it, you can either install the shelf in the .zip :

Copy the .mel as well as the .png file in your shelves and icons folder for instance on windows:

C:\Users\userName\Documents\maya\2012-x64\prefs\shelves
C:\Users\userName\Documents\maya\2012-x64\prefs\icons 

You will have a nez shelf "GJ_Tools" with the lighting preset ("lp") icon.


Or dowload the python script and open it with the script editor: Light Preset Python Script

________________________________________________________________________

The script should work on Windows, Mac and Linux, but I cant check version for mac and linux, if someone has a problem just give me a shout, thanks !


Many options available as :

- Save all lights or only selected lights
- Save only rendering parameters
- Save cameras ( Normal cameras only for now )
- Save perspective view in the preset toggle
- Save all presets in the same folder by default to reduce useless manipulations
- Load a preset from an external .xml file
- Create light objects in your scene directly from the .xml preset file
- UI dockable or not
- 3 Presets groups available
- Save preferences in order to keep options setuped as you want, even if you close maya
-...

Script still in beta, for any problem, drop me an email !

GJ Linear shader for Vray and Mentalray ( Maya )

Here are 2 little Python scripts in order to create automatically shaders with 3 texture files ( Diffuse, Reflection Color and Bump ) as well as 2 gamma correction nodes for Diffuse and Reflection Color.

Select a shader and run the script, if you haven't selected any shader the script will ask you if you want to create a new one.

be carfefull, for the moment the shader works only with Vraymtl and Mia_ shader, not with other shaders ( such as SSS, Light etc. )

TIPS:
By default, the script applies a gamma correction at 0.455, if you want to change this value, before executing the script, type in the Python line in the bottom of maya's UI : gamma_value = "your value" and hit enter. The script will use this value until you either change the value again or re-start maya.

How to use Mental Ray Production shader in Maya

Just a quick message to show how to use hidden MentalRay Production Shader ( More in this .PDF ).

There are a lot of very useful shader hidden in MentalRay such as Rayswitcher, Matte/shadow, Mirror/gray ball etc... but they are for the moment not supported by autodesk.

How to see those shaders in the Hypershade ?

First go in the folder : Program Files\Autodesk\Maya2012\scripts\others and find the mentalrayCustomNodeClass.mel and open it with a text editor.

At the end of the file you will find this line " $enableMAPShaders == 0 ) || " change the "0" to "1" save the file, and restart Maya !

If Node are not displayed in the hypershader you can type in the "mel" input the line : createNode + the name of the node for instance :
