La \u00faltima versi\u00f3n de ZBrush<\/a> inclu\u00eda una serie de novedades entre las que se encontraban los nuevos Trim Brushes, la posibilidad de mantener los poligrupos en DynaMesh sin usar la opci\u00f3n Groups y otras utilidades. Sin embargo, parec\u00eda que la inclusi\u00f3n de estas herramientas hab\u00eda producido la p\u00e9rdida de alguna otra. En concreto, una muy evidente era que el pincel Slice, incluido en la versi\u00f3n 4R2<\/a>, hab\u00eda dejado de funcionar correctamente y el corte ya no separaba las dos porciones de la malla.<\/p>\n

\"Funcionamiento<\/a>

Funcionamiento del Slice Brush en ZBrush 4R6<\/p><\/div>\n

Lo que ocurre es lo siguiente: El pincel Slice Curve crea poligrupos independientes en las superficies internas que se producen al cortar la malla. Es decir, si al principio la malla consta de un solo poligrupo, tras una operaci\u00f3n de Slice en la que parti\u00e9ramos dicha malla por la mitad no tendr\u00edamos dos poligrupos, como visualmente podr\u00eda parecer, sino cuatro. Las tapas internas de cada porci\u00f3n son poligrupos diferentes. Esto se puede comprobar realizando un Split Groups en en submen\u00fa Subtool\/Split. Por ello, cuando tratamos de separar las dos porciones, se genera un puente entre ambas: La tapa de la porci\u00f3n que estamos moviendo no se desplaza, porque no forma parte del mismo poligrupo que \u00e9sta, aunque s\u00ed de la porci\u00f3n. Al estar unido y no moverse, se produce ese arrastre de pol\u00edgonos caracter\u00edstico del fallo.<\/p>\n

<\/div><\/div><\/div>
\"Los<\/a>

Los cuatro poligrupos generados por el corte con Slice.<\/p><\/div>\n

La soluci\u00f3n a este problema podr\u00eda ser en principio agrupar los poligrupos de cada porci\u00f3n. Eso se consigue usando la opci\u00f3n Tool\/Polygroups\/Auto Groups. Pero esta opci\u00f3n no acaba de funcionar del todo, pues deja dientes de sierra en el borde del corte, debido a la asignaci\u00f3n de pol\u00edgonos a cada poligrupo. Es necesario remallar de nuevo para eliminar ese defecto. Lo que curiosamente s\u00ed funciona de primeras es activar Colorize en la malla a cortar. Todav\u00eda no entiendo muy bien por qu\u00e9, pero en ese caso no se generan los poligrupos independientes en el corte, y la herramienta se comporta como en la versi\u00f3n 4R5. Habr\u00e1 que investigar, pero al menos la funcionalidad sigue ah\u00ed!<\/p>\n

Dejo un peque\u00f1o v\u00eddeo explicativo del problema y la soluci\u00f3n.<\/p>\n
