TEnumAsByte< ETextureRenderTargetFormat > RenderTargetFormat
Format of the texture render target. Data written to the render target will be quantized to this format, which can limit the range and precision. The largest format (RTF_RGBA32f) uses 16x more memory and bandwidth than the smallest (RTF_R8) and can greatly affect performance. Use the smallest format that has enough precision and range for what you are doing.
