[SOLVED] How to mask/clipping a GUI?

Questions
19

I need help again :pensive: I’m trying to implement different movement logic for two masks, but only the last wave_2 works, more precisely, wave_1 also works, but according to the movement logic of wave_2. I understand why this happens, but I don’t understand how to fix it :disappointed_relieved:

local camera_gui = state.cameras.camera_gui
render.set_view(camera_gui.view)
