I’ve just started using Blender and the more I use it the more it becomes a necessary tool in the belt. I’m doing some R+D tests right now with Dynamic Paint for a proposal that I’m working on and it works awesome! I’ve done a sample that I’ve loaded into the blog section of my site if anyone wants to take a look. I basically did all the animation in Blender and then exported out to 3ds MAX and rendered in Mental Ray. I plan on staying in Blender once I get more proficient at lighting/rendering. Have a look if your interested.
