I have encountered some problems and don't know how to solve.

If I can get a solution, I will be very grateful.

FATAL ERROR in Room Creation Code for room room_blank

layer_set_fx() - second parameter should be an FX object

 at gml_Script_live_room_loader_add_layer (line 14003) -                             layer_set_fx(l_rl,l_fx1);

Without knowing more specifics or having an example project at hand, be aware that GameMaker will only compile effect types that are used somewhere in the project, so switching effect type to something new requires tweaking.

Thank you. I'm trying to solve the problem.
