Hello,
I understand that your question involves the image that you’ve shown (very nice image you’ve shown) and wanting to set it hidden / visible while in landscape mode.
If you can reference that photo (I’m not sure if you said you were simulating or not) while not simulating, you can use “Set Actor Hidden in Game” and set Hidden to False for Visible and set Hidden True for invisible.
IF you’ve added the picture as a component, you can use “Set Visibility”
If you are simulating, this is easier because things like the Game Mode run, if you have it set by default in the project settings or in the Game Mode Override, the player might spawn in a pooling location, I’m not sure how you’re handling that stage of your project and where would be appropriate to place those “Set Actor Hidden” and “Set Visibility”
Please respond with further details so I can assist you if you choose to continue chatting and I will do my best.
