Validation

Validation is performed during the effect compile. To validate the current technique, specify NULL as the technique handle to be validated.

Validation will fail for any of the following:

• If the specified technique handle does not exist.
• If the application of any state in any pass of the technique fails.
• If device validation fails after the application of all the states in any pass of the technique.
• If the PIXELSHADER or VERTEXSHADER effect states are assigned invalid shaders in any pass of the technique.
• If the device caps do not support cube mapping, and a TEXTURE effect state is assigned a value of type textureCUBE in any pass of the technique.
• If the device caps do not support volume mapping and a TEXTURE effect state is assigned a value of type texture3D in any pass of the technique.
