Hey there, I've been using Carrara since it was Ray Dream Studio 5.0, so you could say that I'm a rather dedicated customer. Let's see here. Things I like are as follows: I like the interface. I've been using it for a few years, so I find it comfortable. I like the shader function. I think that it is built with a lot of options, and functionality. I like the render engine. I get clean, well rendered images at competitive resolution. I like the tree/plant editor. I've made good use of it. I like the fact that the source code is available to third party developers. This frees Eovia to focus on a select few issues at a time, while allowing others to pursue more specific goals. This make the application robust and builds a sustainable community that can tailor adjust its applications based on their needs. This is a winning combination. Things that could use improvements: Particles. This needs some work. I have been requesting improvements since Carrara version 1, under Metacreations. Metaballs. The interface is still awkward, and could be better integrated. I'm sure that this function could be pushed further. Bones. I will grant that you have improved the basic IK architecture. I would still suggest that the bones function could benefit from further attention. These are the three functions that I would like attention given to in version 5. Thank you for your time. Keep up the good coding. Krzysztof Mathews www.firstgearterritories.com
