Hello there!
I got couple of Maya specific questions. I thought I may get best help from here. Namely, I am a XSI user, I've given an assignment to convert XSI scene to Maya. Everything is running smoothly but i got couple of shader questions. Trying to find their Maya equivalent.
I just copied descriptions from XSi manuals to be exact with descriptions:
First one, Sprite shader:
Shader Type: Illumination (surface)
Output: Color (RGB) value
This shader is designed to render a sprite or billboard on a grid. Transparency is infinite, because the shader ignores the Ray Depth settings in the render options. This means that you can have thousands of sprites at different depths and see all of them correctly without having to set extraordinarily high Ray Depth values.
Second one, Ray_Type:
Shader Type: Switch (Tool)
Output: Color (RGB) value
Selects the color or texture to be displayed (output), depending on the type of ray hitting the object.
Name The shader's name. Enter any name you like, or leave the default.
Eye Defines the color when an eye ray is hitting the object.
Refraction Defines the color when a refractive transparency ray is hitting the object.
Reflection Defines the color when a reflective ray is hitting the object.
Shadow Defines the color when a shadow ray is hitting the object.
Photon Defines the color when a final gathering is hitting the object.
Final Gathering Defines the color when a photon ray is hitting the object.
Use Eye ort for final gathering
When selected, final gathering is evaluated through the eye ray port.
Use FG port for final gathering
When selected, final gathering is evaluated through the final gathering port.
Render Tree Usage
In the render tree, use this shader to define a texture or texture effect for the various rays that hit an object. For example, the Reflection input can be a gradient, the Shadow input can be a fractal, and the eye ray can be an image clip. This shader can then be output to either the Surface connection of the Material node or a Color input on a surface shader.
Thx!
