Have you watched Big Buck Bunny, which was done in Blender? It's infinitely better. It's just like watching a Pixar film.
Yes, I know the Blender Open Movies. Most of them are impressive. My favourite is the masterpiece called "Sintel".
Open Projects on Blender Cloud
If you liked "Pigeon: Impossible",
@Nod , you wìll probably like "Agent 327" too ;-)
Anyway, the sense of my post was different.
As far as I know, Blender Open Movies are made to show off Blender's ability to compete with the most used programs in the animation field. They are funded, and have a fair group of artists working on them.
"The Misty Green Sky" and "Rosa" play in a different category. They are the effort of few people, using mainly DS or Poser with 3D models bought on the online stores.
I respect the effort put in "The Misty Green Sky", but it gets very limited results and I'm surprised that it is a product made for selling.
I understand that "Rosa" was made by Jesus Orellana alone (or with just a little help from his friends ;-)), on a Mac he had at home, using Daz Studio with 3D models from the stores, and Blender for modifications, special effects and all. If this is true, I think Orellana's final result is amazing.
The difference must be the talent of the artists involved.
So, It is nice to know that the programs we use, when we use them well, can achieve good quality.
