Volumen de partículas 3D para suciedad y escombros transportados por el agua, renderizado a través de la cámara con viento, turbulencia y desvanecimiento de bordes opcional.
Schmutz (waterSchmutz) llena un volumen cúbico 3D con partículas de larga duración y las renderiza como sprites suaves mediante la entrada de una cámara. Úsalo cuando una placa de agua o una toma subacuática necesite sedimentos flotantes, motas o pequeños escombros que permanezcan en el espacio y se muevan con la toma.
Coloca y orienta el volumen con los límites del cubo, trasládalo y gíralo. La densidad de partículas controla la emisión del volumen del cubo; el tamaño y el rango de tamaño controlan la escala del sprite. La dirección del viento, la escala de turbulencia y la intensidad de la turbulencia impulsan el movimiento. Envolver partículas las mantiene dentro del volumen; el desvanecimiento de bordes suaviza la opacidad hacia los límites. Actualizar partículas reinicia el sistema.
Por defecto, los sprites provienen de una elipse de ruido suave. Habilita los sprites personalizados y conecta una imagen para reemplazarlos. spriteView muestra una vista previa de la ruta del sprite. La configuración de renderizado abarca el formato de salida, el suavizado de bordes, el sobreescaneo, el modo proxy, las muestras, el obturador y las muestras estocásticas. La opción GUI Disable desactiva la cadena de partículas en la interfaz gráfica cuando necesitas una sesión más ligera.
