3d animazione da cinema4d al miscelatore

Question

Ho bisogno di importare un'animazione di maglia da Cinema4D in Blender .

Ho cercato di farlo usando Collada.The Collada 1.3 importatore non sembra fare qualsiasi cosa, l'importatore Collada 1.4 sembra funzionare, ma l'animazione non ha ottenuto importata in Blender.

Dopo aver letto questo post :

Problema risolto!

Nel caso in cui qualcuno viene qui in cerca per la risposta, ho parlato con Otomo via e-mail e ha gentilmente spiegato che il problema sta nel essere file di .dae esportati in modo non corretto da C4D.

Spero Otomo non mente me citando la sua e-mail, solo che non vuole l'altro la gente a sprecare il tempo che ho fatto su tale un problema stupido.

Apri il .dae in un editor di testo e cambiamento:

dati dati

a questo:

Dati dati

Il fps deve anche essere lo stesso in entrambi i c4d e frullatore.

ho provato, ma ottengo un errore:

FEEDBACK: Illusoft Collada 1.4 Plugin v0.3.162 started
The minor version of the file you are using is newer then the plug-in, so errors may occur.

Qualcuno ha incontrato questo problema? Dove posso trovare un importatore Collada più recente? Eventuali suggerimenti su come modificare l'importatore?

Nota: Blender 2.5a2 animazioni importazioni Collada, ma il sistema di coordinate è diverso e non tutte le animazioni riesce a passare. Per esempio, quando ho animare una scatola da 0,0,0 a 100.100.100, rotazione su x, y, z e scalare su x, y, z, in Blender ottengo:. definizione su 1 asse (x, che originariamente è y di cinema 4d), la rotazione è soddisfacente, scala viene ignorato

Answer 1

ho finito per scrivere una sceneggiatura.

ho appena trovato utilizzabile C.O.F.F.E.E. documentazione così è andato avanti e installato py4D .

La documentazione è abbastanza buono e il supporto sul forum è sorprendente.

Ecco lo script corrente:
