I solve this by creating a variable with the type ‘Engine Show Flags Setting.’ Set this variable to an array, then add elements and set them to true or false according to your desired result. For example, Anti Aliasing ‘False,’ Atmosphere ‘False,’ BSP ‘False,’ Cloud ‘False,’ Static Meshes ‘True’ and so on.
In the construction script of the blueprint, get your target scene capture component 2D and call ‘Set show flag settings’ with this array variable."
