I am currently working on building a material library in 3dx completely from scratch and I am looking for some guidance from the experts on best practices and lessons learned. Are people maintaining material libraries in 3dx or are you relying on external tools that are designed for material organization? I have done some preliminary research and it does not look like there is any way to do this nicely in 3dx. The material properties do not map to a 6w tag attribute and it does not seem like there is any way to access this information so it seems like you are limited to just organizing the materials by type i.e. metals, fluids, ceramics, etc. I think it would be nice for users to be able to search for materials based on properties, for example, they want a material that has a density below some value and a strength above another value. Am I dreaming? Is there another license that is needed to enhance the capabilities?
