Get reference to player from another level

I have enabled world composition and need to get reference to my character from another level (which is loaded to the scene). I have a level blueprint which controls sun position on the sky and a variable in my character blueprint which stores global time, so if I unload level with sun and then load it again sun would be in proper position according to time variable on my character. I’ve tried to cast directly, used blueprint interfaces and make custom events, but casting directly and events doesnt work between levels and blueprint interfaces cannot connect with level blueprints.
Sorry for my english.
