Integra el primer plano (FG) en el fondo (BG) con fusión de bordes, sangrado de color y ajuste a múltiples escalas; solo ajusta el primer plano, no realiza una fusión completa.

Ultimerge prepara un primer plano para que se integre mejor con el fondo. No reemplaza una fusión: modifica el primer plano con coincidencia de bordes, sangrado de color del fondo y un pase de ajuste, y luego genera el primer plano ajustado (premultiplicado).

Úselo en placas clave o CG que se lean como recortadas. Blend Edges suaviza y hace coincidir el límite del FG con el BG (tamaño y mezcla). Bleed Color extiende el color del BG hacia el borde con un desenfoque multiescala (tamaño y cantidad). Wrap All agrega un envoltorio multiescala más amplio de BG alrededor del FG (tamaño y mezcla). Una entrada de máscara opcional limita dónde se aplica el efecto.

El procesamiento se realiza mediante el registro (AlexaV3LogC) para los trazados de borde y envoltura. Active el efecto únicamente para inspeccionar el cambio RGB sin el resultado FG completo, y luego ajuste el tamaño y la mezcla de cada sección a su gusto.
