OK so here is an example of how to use props (you can play it in your portal):
INT. ITALIAN RESTAURANT OL - NIGHT with TABLE ITALIAN at layer 10
&LELA spot 1.280 77 -69 in zone 1 AND LELA faces right AND LELA moves to layer 1
&zoom reset
LELA (eyeroll_subtle)
(I hate Champagne)
@add Champagne Flute Filled to LELA
@LELA is idle_cup_worried_loop
LELA
(but I have to drink it anyway because it is Isabella’s birthday)
LELA (talk_cup_toast_happy)
Happy birthday!
@LELA is sip_stemware_neutral
@remove Champagne Flute Filled from LELA
@LELA is idle_armscrossed_neutral_loop
in case you want the glasses to apear on the table only after the toast - simply add the overlays of the champagne after such scene after you have removed the props from the character.
