PortalObject::SetPortalFlags

Defined in: C4Portals.h

Sets the portal flags.

Prototype

void SetPortalFlags(uint32 flags);

Parameters

flags The new portal flags.

Description

The SetPortalFlags function sets the portal flags to the value specified by the flags parameter, which can a combination (through logical OR) of the following constants.

`kPortalLightInhibit`	No lights shine through the portal.
`kPortalStaticLightInhibit`	Only dynamic lights shine through the portal.
`kPortalShadowMapInhibit`	For a direct portal, the portal is not followed when rendering a shadow map. For an indirect portal, shadows are not rendered in the image generated by the portal.
`kPortalFogInhibit`	Do not apply fog through the portal (direct portal only).
`kPortalSkyboxInhibit`	Do not render the skybox through the portal (indirect portal only).
`kPortalOverrideClearColor`	Override the camera clear color when rendering through the portal (indirect portal only).
`kPortalSeparateShadowMap`	An infinite shadow map rendered through the portal is not reused (indirect portal only). This only affects portals whose indirect transform is the identity.
`kPortalAllowIndirectLight`	Allow lights to shine through the portal (indirect portal only).
`kPortalObliqueFrustum`	Use an oblique view frustum when rendering through the portal (indirect portal only).
`kPortalRecursive`	Allow the portal to be rendered recursively (indirect portal only).
`kPortalDistant`	Render only infinitely distant objects, like the skybox, through the portal (indirect portal only).
`kPortalSourceInhibit`	No source audio flows through the portal (direct portal only).
`kPortalForceCameraZone`	The camera regions are rooted only in the target zone (indirect portal only).
`kPortalShadowMapMaxDepth`	Disables an optimization that uses the maximum depth of all rendered geometries to cull infinite shadow cascades (indirect portal only). This applies to indirect portals that do not have the `kPortalSeparateShadowMap` flag specified.
`kPortalFullShadowRegion`	Causes the full-size shadow region to be used on the side of the portal containing a light (direct portal only).
