Methods

GetRenderData(Mode)

Get the render data of a specific mode.

Note: The HDProbe stores only one RenderData per mode, even for view dependent probes with multiple viewers. In that case, make sure that you have set the RenderData relative to the expected viewer before rendering. Otherwise the data retrieved by this function will be wrong.

Declaration
public HDProbe.RenderData GetRenderData(ProbeSettings.Mode targetMode)
Parameters
Type Name Description
ProbeSettings.Mode targetMode

The mode to query
Returns
Type Description
HDProbe.RenderData

The requested render data
Exceptions
Type Condition
ArgumentOutOfRangeException

When the mode is invalid

GetTexture(Mode)

Get the texture for a specific mode.

Declaration
public Texture GetTexture(ProbeSettings.Mode targetMode)
Parameters
Type Name Description
ProbeSettings.Mode targetMode

The mode to query.
Returns
Type Description
Texture

The texture for this specified mode.
Exceptions
Type Condition
ArgumentOutOfRangeException

When thetargetMode is invalid.

PrepareCulling()

Prepare the probe for culling. You should call this method when you update the influenceVolume parameters during runtime.

Declaration
public virtual void PrepareCulling()

RequestRenderNextUpdate()

Requests that Unity renders this Reflection Probe during the next update.

Declaration
public void RequestRenderNextUpdate()
Remarks

If the Reflection Probe uses OnDemand mode, Unity renders the probe the next time the probe influences a Camera rendering.

If the Reflection Probe doesn't have an attached HDAdditionalReflectionData component, calling this function has no effect.

Note: If any part of a Camera's frustum intersects a Reflection Probe's influence volume, the Reflection Probe influences the Camera.

SetDepthTexture(Mode, Texture)

Set the depth texture for a specific target mode.

Declaration
public Texture SetDepthTexture(ProbeSettings.Mode targetMode, Texture texture)
Parameters
Type Name Description
ProbeSettings.Mode targetMode

The mode to update.
Texture texture

The texture to set.
Returns
Type Description
Texture

The texture that was set.

SetRenderData(Mode, RenderData)

Set the render data for a specific mode.

Note: The HDProbe stores only one RenderData per mode, even for view dependent probes with multiple viewers. In that case, make sure that you have set the RenderData relative to the expected viewer before rendering.

Declaration
public void SetRenderData(ProbeSettings.Mode targetMode, HDProbe.RenderData renderData)
Parameters
Type Name Description
ProbeSettings.Mode targetMode

The mode to update
HDProbe.RenderData renderData

The data to set
Exceptions
Type Condition
ArgumentOutOfRangeException

When the mode is invalid

SetTexture(Mode, Texture)

Set the texture for a specific target mode.

Declaration
public Texture SetTexture(ProbeSettings.Mode targetMode, Texture texture)
