Syntax

FRDGTextureRef RegisterExternalTextureWithFallback
(
    FRDGBuilder & GraphBuilder,
    const TRefCountPtr< IPooledRenderTarget > & ExternalPooledTexture,
    const TRefCountPtr< IPooledRenderTarget > & FallbackPooledTexture,
    ERenderTargetTexture ExternalTexture,
    ERenderTargetTexture FallbackTexture
)

Remarks

CAUTION: use this function very wisely. It may actually remove shader parameter validation failure when a pass is actually trying to access a resource not yet or no longer available.
