Shader Type: RealTime
Output: RealTime
Location: This shader is still supported as a legacy shader, but has been removed from menus in Softimage. Scenes containing this shader will display correctly. Load this shader into the render tree from Nodes > RealTime > OpenGL > More.
Defines and executes a single OGL rendering pass by determining the OGL state, and the drawing.

Name |
The shader’s name. Enter any name you like, or leave the default. |
|
Normal |
Specifies whether or no to use normal data when drawing. |
|
UV |
Specifies whether or no to use UV data when drawing. |
|
Vertex Color |
Specifies whether or no to use vertex color data when drawing. |
Blending
OGL Blending functions add the RGBA values of incoming (source) pixels to those of the frame buffer (destination) pixels. Both source and destination pixels can be multiplied by one of a number of different multipliers, in order to achieve specific blending effects, like transparency for example.
|
Enable Blending |
Switches the OGL blending function on. |
|
Source |
Specifies the multiplier for the incoming, or source pixels. |
|
Destination |
Specifies the multiplier for the frame buffer, or destination pixels. |
|
Culling |
Specifies whether a part of the object should not be drawn. When set to NONE, the entire object is drawn. |
|
Depth Test |
Toggles depth testing on or off when drawing a pixel. When enabled, a pixel will only be overwritten if it’s distance according to the camera (depth) is smaller then the existing pixel depth stored in the depth buffer. |
This shader can be used to execute a drawing pass on any group of RealTime shaders. Typically, an OGLDraw shader is used to draw each successive layer in the shader tree. Layers are blended together to create the final effect, and a final OGLDraw shader is connected to the Material node’s Realtime port sot that the entire effect can be drawn.
