I have delay when play a template on new layer and if there is nothing on the screen. If there is already something on that layer or on someone other layer (on screen) then everything is going as it should.
I see. That is normal, it takes a moment to initialze the layer. That is why you should reuse layers and not create a new layer everytime you play a template. You can try to load the template before you play it, that should also help.
Thank you @didikunz. I found solution. Adding empty (only Load function) template on some layer which is not used and after that everything is going instantly.
