I'm trying to set the variant subsystem of a simulink model from matlab, by the set_param function.
The model has some already done subsystems and I added 2 new subsystems (test1 and test2); If I set one of the already done subsystems it works, but if I try to set one of the new variant subsystems it doesn't works.
I called the new subsystems test1 and test2, also in the variant choice table of the block parameter.
If I use this command it works:
set_param(['sm_car' '/World'],'popup_scene','Road Two Lane');
but with this command it doesn't works:
>> set_param(['sm_car' '/World'],'popup_scene','test1');
The error is:
Invalid setting in Environment block (mask) 'World' for parameter 'popup_scene'
Caused by:
Option specified is not valid.
Why?

It looks like you have a mask on a subsystem and are using that mask to control the variant choice. You need to associate that mask variable with the variant selection. This link shows a couple of different ways to do this. The first example looks like what you need.

Thank you so much! Just needed to add the new scene names in the mask parameter type options!
