Syntax

static UTextureRenderTarget2D * GetOrCreateTransientRenderTarget2D
(
    UTextureRenderTarget2D * InRenderTarget,
    FName InRenderTargetName,
    const FIntPoint & InSize,
    ETextureRenderTargetFormat InFormat,
    const FLinearColor & InClearColor,
    bool bInAutoGenerateMipMaps
)

Remarks

Creates a transient render target of the proper size/format/... or returns the existing one if it's compatible. InRenderTarget is read-only so it's up to the caller to decide to update or not the RT. Usually, the calling code will be : RT = FWaterUtils::GetOrCreateTransientRenderTarget2D

Returns

a compatible transient render target if InMaterialInterface is size/format/... is valid, nullptr otherwise

Parameters

Parameter	Description
InRenderTarget	is the current render target currently used. It will be the one returned if it's already compatible with the size/format/...
InRenderTargetName	is the UObject's name in case we need to create a MID
InSize	is the render target's size
InFormat	is the render target's format
InClearColor	is the render target's default clear color
bInAutoGenerateMipMaps	is for generating mipmaps automatically after rendering to the render target
