virtual void RHIReadSurfaceData &40;     FRHITexture &42; Texture,     FIntRect Rect,     TArray< FColor > & OutData,     FReadSurfaceDataFlags InFlags &41;

Remarks

Reads the contents of a texture to an output buffer (non MSAA and MSAA) and returns it as a FColor array. If the format or texture type is unsupported the OutData array will be size 0
