Procedurals can never be shared between different programs because they are themselves unique programs.

That is, when you create a procedural material, procedural terrain or anything else procedural, you are causing Vue to write a little program describing that material, function, terrain, etc. - instead of using physical things, like images as textures or height maps and such. You could say that these are 'virtual' textures, virtual terrains, etc.

These little programs allow a lot of advanced features in your scenes that wouldn't be possible otherwise. But, every graphics application that creates procedurals does so differently - there are no industry standards being enforced here.

So, naturally a procedural written in one program cannot be understood by another program. The exception is when a big effort happens between the engineers of one company and another, in order to integrate two programs, such as the way Poser figure import was integrated into Vue.

Hope that clarifies things.
