Lights

LIGHTS

FurryBall has almost full support for these light types:

• Ambient
• Directional
• Point
• Spot

All of these light types support texture in Color attribute and Maya intensity curve in Intensity attribute.

Attributes

Ambient Light

All attributes (except Ambient Shade) from Ambient Light Attributes section are supported. Supports texture in color attribute to allow IBL (Image Based Lighting). This texture is mapped by spherical coordinates. No texture support for any other attribute yet.

Directional Light

All attributes from Directional Light Attributes section are supported. No texture support for any attribute yet except color texture.

Point Light

All attributes from Point Light Attributes section are supported. No texture support for any attribute yet except color texture.

Spot Light

All attributes from Spot Light Attributes section are supported. No texture support for any attribute yet except color texture.

Shadow Attributes

FurryBall uses shadow maps when shadowing, these attributes are supported by FurryBall in Depth Map Shadow Attributes in spot, directional and point light shape node:

• Shadow Color - Use HSV color model for setting this attribute, because S (saturate) value will be causes "transparency" of shadow.
• Use Depth Map Shadows
• Resolution - The higher resolution, the more precise the shadows, with less artifacts. But very big shadow maps consume a lot of memory.
• Use Auto Focus
• Focus
• Filter Size - filter size is changed for keeping shadow blur in each resolution, hence filter size value 1 corresponds to one pixel in resolution 1024, 2 pixels in resolution 2048 etc.
• Bias - Shadow Depth Bias is necessary to prevent shadow map artifacts such as acne. However, other artifacts such as "Peter-Panning" may appear, if this value is too high.

See Maya documentation for description of these attributes. See Light Node section for more details about soft shadows and variable penumbra shadows attributes.

Special Attributes

There are several special attributes added by FurryBall plugin, see Light Node section for more details.
