Hola , tengo problemas al intentar editar las particulas , no me sale el editor ni las particulas y me da esto en la consola:

Utilizo la ultima version unity3d 2018.3.2f1 y la ultima version de obi cloth

Edit: solucionado , Elimine la carpeta manualmente y reinstale obi cloth y se soluciono el problema.

Hola , sigo con los problemas , el menu de edicion ya me aparece pero al intentar editar las particulas el modelo se queda en gris y no aparecen las particulas , aparte que el editor se relentiza , alguna solucion?

Hola,

Aparece algún error en la consola? de no ser así, asegúrate de que tu modelo tiene normales válidas, y que está activo el modo "read/write Enabled" en las opciones de importación, ya que las normales se utilizan para mostrar sólo las partículas que están mirando a cámara.

un saludo,

Hola , gracias por responder , el problema se soluciona recalculando los normales desde unity3d desde las opciones de importacion de modelo , modificando la opcion de import a calculate.

En ese caso, tu modelo no tenía normales, lo cual es bastante desaconsejable. Lo típico es exportar un modelo con normales y tangentes, ya que te permite controlar el aspecto de su superficie y cómo se ve bajo iluminación. Sólo en caso de que no puedas modificar el modelo y éste no contenga información de normales, deberías pedir a Unity que las calcule por ti en lugar de importar las del modelo.

Hola , pues los problemas siguen igual , aun que el modelo tenga bien los normales o se calculen desde unity el editor sigue  sin mostrar nada en algunos modelos , si no optimizo el modelo desde el obi cloth el editor no sale y da error que luego pondre , si lo optimizo no da el error pero no se pueden editar las particulas por que no salen , se pone el modelo en gris  , este es el error que me da al no optimizar desde el obi:

Te e puesto una foto de el modelo que utilizo y si que tiene los normales , no se si sera por la resolucion que tiene el modelo , en la foto sale como todo parece estar en orden.

Mismo modelo con el systema cloth de unity y si que me deja asignar las particulas , asi que si fuera el modelo que fallara no funcionaria tampoco el systema de unity , no se que sera pero metiene ya un poco loco esto   , gracias

Si el modelo que has importado en Unity tiene normales o no, es totalmente imposible saberlo mirándolo fuera de Unity ya que una vez exportado los datos no son los mismos que ves en tu programa de modelado. Tienes que comprobar que el fbx/obj/formato que exportes las contenga, y que Unity pueda importarlas. Lo más rápido es que digas a Unity que importe las normales del archivo, y veas si está bien iluminado al instanciarlo en la escena. Si la iluminación no es correcta, no tiene normales.

El sistema de cloth de Unity puede trabajar con cualquier geometría, ya que no requiere que la geometría sea 2-manifold ni necesita normales, en cambio Obi sí. Comprueba que los modelos que usas no sean non-manifold. Al generar el ObiMeshTopology, te avisa si es capaz de encontrar la fuente del non-manifold (aunque muchas veces no es capaz si el modelo tiene malformaciones). Esto lo puedes comprobar en casi cualquier programa de modelado, haciendo una limpieza automática de la malla.

Edit: la malla que muestras en la imagen tiene más de 30000 triángulos, no te aconsejo que la simules directamente porque el rendimiento va a ser pésimo. Simula una versión low poly y utiliza proxies para transferir la simulación a la malla en alta resolución:
