Convert anFPropertyvalue to a value compatible with the shader parameter data layout. The InValue parameter should point at the memory location governed by theFPropertyfor this data type, and OutConvertedValue is an array to store the bytes for the converted value. If the function failed, a nullptr is returned and the state of the OutConvertedValue is undefined. Upon success, the return value is a pointer to the value following the converted input value, and the converted output value array will have been grown to accommodate the newly converted value.
